New Mix 2s screen turns on accidentally

Hello. I've installed MIUI 12.5.1stable release on my Mix 2s. After that, the screen started to turn on in random time. Need help.

I found the problem. It was Viber app. I turned off all its notifications, but this app overwrites the "turn on screen when notification received" option. So, when the screen has been turned on by Viber notification, I saw nothing on the screen .
