A. Ensure that your app is updated to the latest version. Go to the App Store, search for Fliff, and check if an update is available. If so, install it. This can help fix bugs that may cause bets to disappear.
B. Try clearing the app's cache. Go to your iPhone's Settings > General > iPhone Storage > Fliff. Tap on 'Offload App' to clear the cache without deleting your data. Reinstall the app afterward.
