I have finally upgraded my device to Android 15.
I'm thinking of releasing the next beta version with only changes to the screen, rather than adding or improving functions.
The initial settings screen and error log screen can be done without connecting to MusicBee, so I've already finished improving them using an emulator.
I'm thinking of applying the same improvements to the remaining screens, and then releasing the beta version after checking it on Android 12, 14, and 15 devices.
