How can I clear the Steam mobile app's cache and data?

Clearing the cache and data can resolve app-related glitches. On Android, go to Settings > Apps > Steam > Storage and tap 'Clear Cache' and then 'Clear Data'. On iOS, you'll need to delete and reinstall the app as iOS doesn't offer a direct cache clearing option. Note that clearing data will log you out, and you’ll need to re-enter your credentials.
