A. 1. Check your internet connection: Ensure that your Wi-Fi is stable and has sufficient speed. You can do this by running a speed test on your iPhone. If the speed is low, try moving closer to the router or resetting your router. 2. Clear the Apple TV app cache: Go to Settings > General > iPhone Storage, find the Apple TV app, and select 'Offload App'. This will clear the cache without deleting your data.
