Hello kjvdven,
Welcome to Apple Support Communities!
We want to help resolve the issue so you can use AirPlay with your devices.
Make sure you're taking the steps here to properly connect:
"Stream video from your iPhone, iPad, or iPod touch to a TV
- Connect your device to the same Wi-Fi network as your Apple TV or AirPlay 2-compatible smart TV.
- Find the video that you want to stream.
- Tap AirPlay
. In some apps, you might need to tap a different button first.1 For example, in the Photos app, tap Share
, then tap AirPlay
. - Choose your Apple TV or AirPlay 2-compatible smart TV.
To stop streaming, tap AirPlay
in the app that you're streaming from, then tap your iPhone, iPad, or iPod touch from the list."
This Apple Support page has the full details: Use AirPlay to stream video or mirror the screen of your iPhone, iPad, or iPod touch - Apple Support
If the issue continues, check for any pending updates to your Apple TV and other devices. Try restarting them as well. We hope these steps can help isolate and resolve the issue so you can use your Apple TV and screensaver without any issues.
Cheers!
