Hello @JoeKun, I get the same error on a device in an app I uploaded on TestFlight. Is there anything I can do to debug it? At the moment I don't have any device with iOS 15, nor macOS 12. Thanks. Best regards,

Same here. I tried also on real device, but the PiP button in the AVPlayerViewController doesn't show up. I am on the public version of iOS 14.0. Can not believe we are in this situation.
