Hello Gaforbes,

Thanks for connecting with Apple Support Communities.

We'd like to provide you with some guidance . First, we suggest that you try restarting your Apple TV.

Restart Apple TV

"Do any of the following:

• Press and hold both the Back  (Siri Remote 2nd generation or later) or (Siri Remote 1st generation) and TV   buttons on the Siri Remote until the Apple TVstatus light blinks rapidly.
• Disconnect Apple TV from the power outlet, wait five seconds, then reconnect it.
• Open Settings  on Apple TV, go to System and select Restart."

If the issue persists," try resetting Apple TV to its factory settings. When you reset Apple TV, all data is erased, including your accounts and configuration.

You can also reset your Apple TV and update its software at the same time.

You can use your iPhone or iPad to set up your Apple TV for faster recovery. See the Apple Support article If your TV shows an iPhone next to an Apple TV.

Reset Apple TV

1. Open Settings  on Apple TV. 
2. Go to System > Reset, then select Reset. 
3. Resetting Apple TV and restoring it to factory settings can take some time, so be patient. If Apple TV still doesn’t respond, do one of the following:

• If you have an Apple TV 4K: Contact Apple TV Support.
• If you have an Apple TV HD and a Mac with macOS Catalina or later: Disconnect the power and HDMI cables from Apple TV. Connect one end of a USB-C cable (sold separately) to Apple TV and the other end to your computer. Open the Finder on your computer, select Apple TV in the sidebar, then select Restore. If that doesn’t work, contact Apple TV Support.
• If you have an Apple TV HD and a PC with iTunes or a Mac with macOS Mojave or earlier: Disconnect the power and HDMI cables from Apple TV. Connect one end of a USB-C cable (sold separately) to Apple TV and the other end to your computer. Open iTunes on your computer, select Apple TV in the Source list, then select Restore. If that doesn’t work, contact Apple TV Support.

Reset Apple TV and update software

1. Open Settings  on Apple TV. 
2. Go to System > Reset, then select Reset and Update. 
3. Selecting this option restores your Apple TV to factory settings, erases all settings and information, and updates to the latest tvOS version."

We hope this helps.

Have a wonderful day!
