Notifications don't sound if Developer option "Skip screen lock" is set (RN7, x.eu 20.12.9)
A problem I found on the Redmi Note 7 running xiaomi.eu 20.12.9:
Using the phone without security, I selected the Developer option "Skip screen lock" so that I don't need to swipe up on switching the screen on. I then noticed that notification sounds were not playing (everything else was OK, sounds On in Settings, nothing changed from before when notification sounds worked). Switching off "Skip screen lock" restored notification sounds. (It took me a couple of hours to work out what was happening.) I have no reason to think that this is a new problem as I hadn't used this setting before. This can clearly be described as a bug; perhaps it is the reason that "Skip screen lock" is not a standard Setting, but for developers only.
(I didn't test comprehensively, just with Google Keep Notes and Missed Notifications Reminder.)
Assuming that this is something that others can replicate, I don't know if it is something for xiami.eu or Xiaomi to investigate, or simply a not-well-supported developer option that's not going to change.
