Thanks for reporting. Working normally here on test devices. What phone do you have?[BUG REPORT]
After the latest update, "Hide when foreground" option works wrong.
Popup notification of the foreground app isn't shown if I turn back to home screen via home screen button/gesture. To see the popup, I have to open another app or lock and unlock screen.
In short, DynamicSpot sees the app as if it's still running on foreground even if I've turned back to home screen.
1) Open YouTube Music > Play music (or maps, or clock, or phone call etc.)
2) Turn back to home/main screen of the phone. Music player/clock/navigation/phone etc. popups aren't shown.
3) Open another app or lock/unlock screen, then popup notification is shown as it should be.
