iPhone 12 Mini
iOS 15.3, Spotify 220.127.116.114
My Question or Issue
The Spotify app stops playing to AirPlay devices on the same network for an unclear reason. When the phone is restarted, Spotify will play on AirPlay devices for an indeterminate amount of time, but then goes back to being unable to play until the phone is again restarted.
When using the devices menu, I can select the AirPlay device I want to use — the device even seems to acknowledge that something is attempting to play on it (e.g., the light on top of a HomePod Mini illuminates) but no sound comes out and there is no option to adjust the volume from the AirPlay devices list.
I have confirmed that other apps are able to AirPlay from my phone to these devices, and that other iOS and macOS devices are able to AirPlay as well. The issue seems exclusive to the Spotify app on my phone.
