no need to root, you can either collect logs on-device with logfox or use regular adb. It’s still a handful for sure.
I get this right, it crashes on launching just any track, so you’re barred from listening atm? one still kind of user-friendly way is to hop back half a year or year in version and check if it still works. This needs prior uninstall of the app as Android doesn’t allow downgrades in-place. Apkmirror is fine for getting older apks - they look for certificate signature continuity
