I experienced this first after rebooting my phone. After that the phone keeps opening the Spotify Connection Screen and immediately closes it again. This keeps itself in a loop. While the Loop is happening the phone is pretty much unusable.
I tried to reinstall Ratio and it immediately returns to the same loop as described before
If I disable the Spotify Widget from The Root and restart Ratio it doesn’t get in that Loop.
I spammed clicking on the screen where normally the “Authorize” Button of the Connection Screen would be and it got accepted. Since than I didn’t see the Spotify Screen anymore.
It happened on a Pixel 4 XL if it’s maybe device specific.
