Unfortunately, this is the least successful build for me for a while (Samsung S22 / Android 14). As well as the longstanding problem of crashes reported by the system, it now dies after a minute or so when put in background. In addition, whenever I go back to the app to play something after a break, it pretends to play (the circle spins briefly) but does nothing - I have to close and restart the app.
Edit: This latter behaviour appears to happen regardless of battery settings. In fact, having set to unrestricted, the app just died when brought from background to play, rather than giving the spinning circle. Something is definitely broken in this build regarding the background behaviour @ivan .
