Why Are My Twitter Notifications Not Working?

The short version: Twitter (X) notifications usually stop because of one of five things: app-level push permissions, in-app notification filters, a muted or quality-filtered account, a background data restriction on your phone, or a quiet logged-out session that never fully reconnected. Work through them in that order and you will fix it in under ten minutes, no reinstalling required.

Start by working out which notifications are missing

Before you touch any settings, be specific about the problem. "My notifications aren't working" could mean three completely different things, and each one has a different fix:

• You get nothing at all, not even a badge on the app icon
• You get the badge but no banner, sound or lock screen alert
• You get alerts for likes and replies but not for a specific account you follow

Say you run a small bakery account with 4,000 followers and you've noticed you stopped getting pinged when a food blogger with 60,000 followers replies to you, but you still get notified when your mate comments. That's not a broken app. That's X quietly deciding the food blogger's content doesn't meet whatever it thinks you want to see, or you've accidentally filtered quality replies out of your main feed. Two completely different problems, two completely different fixes, and knowing which one you've got saves you from randomly toggling settings for twenty minutes.

Step 1: Check the operating system permission first, not the app

This is the step people skip because it feels too basic, and it's the one that fixes it roughly 60% of the time in my experience helping people troubleshoot this exact complaint.

• On iPhone: Settings, then Notifications, then X, and confirm "Allow Notifications" is on, with Banners, Sounds and Badges all ticked
• On Android: Settings, Apps, X, Notifications, and check nothing has been set to "Silent" or switched off entirely
• Check Do Not Disturb or Focus modes aren't silently excluding the app, which happens a lot after a phone software update resets your custom exceptions

Phone updates are the quiet culprit here. Apple and Android both have a habit of resetting notification permissions or Focus mode exceptions after a major OS update, and nobody checks this because the app itself hasn't changed. If your notifications vanished right after your phone nagged you to update, start here.

Then go into X's own notification settings

Inside the app: tap your profile icon, go to Settings and privacy, then Notifications, then Preferences. From here check:

• Push notifications are toggled on for the categories you care about (Likes, Replies, Mentions, New followers, Posts from people you follow)
• "Quality filter" isn't hiding the content that's missing, which lives under Notifications, Filters
• You haven't accidentally muted a specific keyword that's catching the posts you want to see, which is worth checking against your muted words list if you've been cleaning up your feed recently

Here's the uncomfortable bit most guides won't say plainly: X's notification system is not fully reliable even when every setting is correct. It throttles push notifications based on what it thinks will bring you back to the app, not purely on what you've asked for. If you follow 800 accounts and only ever get notified about the same 15 people, that's not a bug, that's the algorithm deciding those 15 are the ones worth interrupting you for. You can fight it with settings but you can't fully switch it off. Anyone telling you there's a toggle that guarantees every notification arrives is not being straight with you.

Check whether it's one account, not the whole platform

If the missing notifications are tied to a single account, check three things in this order: have you muted them, are they muted on a specific word that's in their bio, and has X quietly reduced their reach because of low engagement on their recent posts. If you want to see who's quoting or engaging with your own posts rather than relying on notifications at all, the quote tweet search method is more reliable than waiting for a push alert, because it pulls from search rather than the notification queue.

A step-by-step worked example

Imagine you manage social for a small gym with 2,000 followers and you've stopped getting notified when members tag the gym in their workout posts. Here's the order I'd check it in:

1. Confirm the OS permission is on (2 minutes)
2. Check Settings and privacy, Notifications, Preferences, and make sure "Posts you're tagged in" is ticked (1 minute)
3. Search the gym's handle directly using X's search bar with "to:yourgymhandle" to see if the tagged posts even exist, because sometimes people think they tagged you but typed the handle wrong (2 minutes)
4. Log out and back in once, which refreshes the push token your phone registered with X's servers (1 minute)
5. If still nothing after 24 hours, reinstall the app, which forces a fresh registration

That's five steps, under ten minutes of actual work, and it covers the overwhelming majority of cases. For a longer reference covering iPhone, Android and web separately, the full notifications troubleshooting guide walks through platform-specific settings in more detail than I've got room for here.

When it's not notifications at all, it's the app

Sometimes what looks like a notification fault is the app failing to sync in the background, which shows up as missing notifications but is really a connectivity or app-performance issue. If your feed itself feels slow, posts aren't loading, or the app crashes when you open it, that's a separate problem and worth ruling out with the X app troubleshooting steps before you keep blaming notification settings specifically.

The data and battery settings nobody thinks to check

On Android especially, battery optimisation settings can stop apps from running in the background, which kills push notifications even though every in-app setting looks correct. Go to Settings, Battery, and check X isn't restricted or put to sleep. On iPhone, check Settings, General, Background App Refresh, and make sure X is switched on there too. If you're on a work or school wifi network with strict firewall rules, that can also block the push notification service entirely, which is worth testing by switching to mobile data for an hour and seeing if anything changes.

If you're doing this for business, don't rely on notifications at all

If you're using X for actual business engagement, replying to customers, tracking mentions of your brand, checking how a live session performed after you went live on X, or watching impressions on a launch post, building your workflow around push notifications is a mistake regardless of whether they're working today. Notifications get throttled, delayed, or dropped by the platform's own algorithm even when every setting is correct. Set a recurring 15-minute block twice a day to check mentions and replies manually through search instead. It's more reliable than waiting for your phone to buzz, and it means a quiet notification bug never costs you a customer reply that should have gone out within the hour.

Frequently asked questions

Why have my Twitter notifications suddenly stopped working?

The most common cause is a phone OS update resetting app permissions or Focus mode exceptions, followed by an in-app setting like the quality filter or a muted keyword catching content you want to see.

Does logging out and back in fix Twitter notifications?

Often yes, because it forces your phone to re-register its push notification token with X's servers, which clears out a stuck or expired connection that settings alone won't fix.

Why do I only get notifications from some people I follow?

X's algorithm decides which accounts are worth interrupting you for based on your past engagement, not purely your settings, so it's normal to stop getting pushed alerts for accounts you rarely interact with even though you still follow them.

Is it worth reinstalling the X app to fix notifications?

Yes if logging out and in hasn't worked after 24 hours, because reinstalling forces a completely fresh registration with the push notification service and clears out any corrupted local settings.
