accepting terms and conditions, how do i do this

Hello Readfield5,

Welcome to Apple Support Communities. When you see this pop-up, do you see an OK button or anything similar? If so, does selecting that option result in the same message reoccurring? If you are not able to see an OK button or this continues, your Apple TV may benefit from a restart if you haven't restarted in a while. A restart may seem simple but can be beneficial for many issues. Guidance below is from How to turn off or restart your Apple TV - Apple Support.

"Restart your Apple TV

If your Apple TV isn't responding, restart it with your remote:

• With your Siri Remote (2nd generation or later) or Apple TV Remote (2nd generation or later)*: Hold down the Back  and TV/Control Center  buttons. Let go when the light on your device flashes.
• With your Siri Remote (1st generation) or Apple TV Remote (1st generation)*: Hold down the Menu and TV/Control Center  buttons. Let go when the light on your device flashes.
• With your Apple Remote (aluminum or white): Hold down the Menu and Down buttons. Let go when the light on your device flashes."

If that doesn't help, perhaps signing out of iCloud and then back in will result in the terms and conditions pop-up, allowing you to accept. Steps below are from Sign out of iCloud on your iPhone, iPad, iPod touch, Apple TV, or Mac - Apple Support.

"Sign out on your Apple TV

1. Go to Settings > Accounts > iCloud.
2. Select Sign Out."

Then, sign back in and test. We hope that helps.

All the best.
