Hi,

For the past week my spotify app has crashed everytime that I have the screen on (it crashes when browsing spotify, when I open other apps, or when doing nothing, as long as the screen is on). The only time that it doesn't crash is when the screen is turned off/locked. The app still appears in the lock screen.

I've checked through the battery settings and battery optimisation, etc, isn't turned on and I have plenty of memory left.

Could someone please advise? Thanks.

Edit: I've also tried a fresh reinstall, etc and I'm not logged in elsewhere either.
