Background playback with screen locked and off pausing audio after 10-15 seconds

Background playback with the screen locked and off is still not working on the latest TestFlight release on the iPhone (2025.22.0). It pauses the audio 10-15 seconds into playback after the screen turns off. I really hope this gets fixed by the next release as the last version with this working correctly (2025.16.0) expires in 12 days. The app will become largely useless to me on iPhone as that is my biggest use case for it there. I download YouTube videos to my server and usually listen to them while doing other things or on walks. I have to keep my screen on to keep the video playing on the Lock Screen, which obviously destroys my battery. Whatever was changed with background playback from 2025.16.0 to 2025.17.0 is what broke it.

Background playback not working on Apple TV either
