Thanks, that worked for me too! Only XposedGmsCore-UnifiedNlp is not working correctly.
Check step ‘UnifiedNlp location’ failed. Your location were not found. Make sure you added at least one backend
Also the microG self check says that UnifiedNlp is not registered and that getting a location wasn’t possible.
I have multiple backends installed via F-Droid and rebooted multiple times. I never had this problem with Android 6 and am now facing this on two Fairphones 2. Has anyone an idea what to try next?
