A. 1. Restart the app: Close the app completely and reopen it to see if the ad refresh issue resolves itself. 2. Check your internet connection: Ensure you have a stable internet connection, as poor connectivity can affect ad loading.

B. 3. Clear app cache: Go to Settings > General > iPhone Storage, find the Hoop app, and tap on it. If there’s an option to 'Offload App', do that to clear some cache without losing your data.
