One week after Android 9.0 I have the following problems. My screen when locked doesn"t show anything anymore..Always on display is turned on and all the settings are correct. The second, I play chesswithfriends...after android 9 there are no notifications anymore, worse I have to close the app and restart to see any moves. All the settings are correct, also in the app. This is the only app that gives me this problem. I did empty my phone cache already and tried a lot off settings. Does anyone recognize this?
