If the mobile app freezes on the splash screen or closes immediately, start with the basics: clear the app cache, force-stop it, and relaunch. On Android go to Settings → Apps → AccuWeather → Clear Cache. On iOS, delete and reinstall the app. Make sure the app version is up to date — outdated builds often lose compatibility with the API backend.
The forecast shows yesterday's data or simply stops updating. This usually means the app lost its background data permissions. Check that AccuWeather is allowed to use mobile data in the background and that battery saver mode isn't blocking network access. On Android, disable battery optimization for the app specifically.
The app keeps showing the wrong location or defaults to a distant city. Make sure location permissions are set to "Always" or "While using the app" — "Only once" breaks automatic detection. Also check that GPS is enabled and that the device has a stable internet connection, since the service relies on both to resolve your position accurately.
Severe weather alerts and daily forecast push notifications stop coming through. Go to the system notification settings and confirm that AccuWeather has full notification access. On Android 13+, the app requires explicit notification permission that isn't granted automatically after reinstall. Also check Do Not Disturb schedules — they silently swallow weather alerts.
Pages on accuweather.com hang mid-load or display broken layouts. This is almost always a browser cache issue. Hard-refresh the page with Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac). If that doesn't help, open the site in a private/incognito window — if it loads fine there, the problem is a corrupted cache or a conflicting browser extension.
