It's genuinely annoying when Instagram isn't working — especially when it worked perfectly yesterday. The reassuring news is that issues like this are almost never serious. In the large majority of cases the culprit is a temporary network hiccup, an app that's fallen behind on updates, or a single setting that's quietly switched off. Below is a calm, ordered checklist that resolves it for most people — start at the top and stop as soon as it's fixed.

A quick word on Instagram specifically: it's photo and video sharing with direct messages, stories, reels and 'close friends', which shapes what tends to go wrong. As a messaging app, most Instagram problems are about messages not moving — syncing, notifications and connectivity — rather than the app failing to open at all, so pay particular attention to the connection and background-data steps below. Instagram shows 'active now' / last active unless activity status is turned off.

First, work out what's actually wrong

Instagram Notifications Not Working? Here's How to Fix It — illustration

When Instagram isn't working, the cause is usually one of a small set: a connection problem, an out-of-date app, a permission or background setting, a corrupted cache, or a server outage on Instagram's side. The ordered checklist below works through them from quickest to most thorough — stop as soon as one resolves it.

The 60-second checks

Start with the three quick checks below — between them they resolve a large share of problems before you touch a single setting:

  1. Restart the phone. The oldest trick in the book, and it endures because it works: a restart clears temporary memory and resets background processes that may be stuck.
  2. Check your connection. Toggle Wi-Fi and mobile data off and back on, or switch between them. A surprising share of ‘app not working’ problems are really connection problems in disguise. Try loading a web page to confirm the internet itself is fine.
  3. Fully close and reopen the app. Don't just minimise it — swipe it away from the recent-apps view and open it fresh. This clears a lot of momentary glitches.

Update the app and your phone

Check permissions, notifications and background data

If the symptom involves notifications, photos, the camera or the microphone, the cause is very often a permission that's been turned off — sometimes by an update, sometimes by an accidental tap. Open your phone's settings, find Instagram, and confirm it has what it needs: notifications enabled, plus access to whatever the affected feature requires.

Two settings catch people out repeatedly. On both platforms, aggressive battery optimisation can throttle an app in the background, which is a frequent reason notifications arrive late; allow Instagram to run unrestricted in the background if alerts are delayed. And background data being switched off (or Low Data Mode being on) can stop an app syncing until you open it. Re-enable both for Instagram and many ‘delayed’ or ‘not updating’ issues vanish.

Clear the cache (Android) or offload (iPhone)

A corrupted cache is a classic cause of an app misbehaving. On Android, go to Settings → Apps → Instagram → Storage and tap Clear cache — this removes temporary files only and won't delete your messages or sign you out. Avoid ‘Clear storage/data’ unless you're prepared to set the app up again. On iPhone there's no direct cache button, but offloading the app (Settings → General → iPhone Storage → Instagram → Offload App) reinstalls it while keeping your documents and data, which achieves the same refresh without losing anything.

Rule out a server outage

Sometimes the problem isn't your phone at all. If Instagram is down for everyone, no amount of fiddling on your end will help. A quick search for “Instagram down”, or a glance at an outage-tracking site or Instagram's official status account, tells you whether the service itself is struggling. If it's a widespread outage, the only real fix is patience — try again in a little while.

The reliable last resort: reinstall

If you've worked through everything above and Instagram still isn't working, uninstall Instagram completely and reinstall it fresh from the app store. For most apps your account and messages are stored server-side or backed up, so a clean reinstall won't lose them — but if the app keeps anything only on the device, confirm a backup exists first. A fresh install clears out any deeper corruption that a cache-clear couldn't reach, and it resolves the stubborn cases that survive every other step.

If it still won't work

On the rare occasion none of this helps, the issue may be account-specific (try signing in on another device to check), or tied to a recent OS update with a fix still pending. Contacting Instagram's official support with the exact symptom and your device model is the right final step — and far wiser than installing random ‘fixer’ apps, which rarely help and sometimes make things worse.
