I can’t airplay stream since Apple TV updated to ios16

Hey there kallywally,

While we're unsure of what occurs when you try using AirPlay as you didn't mention those details, nor do we know which device you're trying to use with your Apple TV, let us know those details and more about what's happening to help us better understand the issue occurring.

In the meantime, we 'd like to rule out some general possible causes by confirming the following:

1. Have you already restarted both your Apple TV and the devices you're trying to use with it? Just in case, here's how to Restart Apple TV.
2. You mentioned updating your Apple TV to tvOS 16, but is tvOS 16.0 the exact version showing under Settings > General > About in your Apple TV model?
3. The latest versions for other devices are macOS 12.6, iOS 16.0.2, and iPadOS 15.7. Are these the exact version numbers installed on your other devices?

Cheers!

Can you explain more about the problem? Does the Apple TV appear in the device list on the iPhone? What happens when you select the Apple TV from the iPhone?
