This happens automatically everytime. The notification automatically goes to totally white even when the notification color is selected to auto/black. And when it happens the play,pause,next song,previous song and the exit button doesn't work from the notification panel. I'm using alpha-build-703 and the android version is 8.1.0. I bought powerapm just because i loved it. But there's no update of this app. The bugs are still there for a long time. What the developers are doing. I didn't play for these bugs. Please fix those bugs and release update.
