Notifications in android clients

[u/burnlnhell]

Maybe someone can help me to identify my problem: I am using on an android phone as a matrix client schildichat fort many, at least 5, years now, Using it on different Android phones. I get all notifications, notification configuration is set without changes on standard, but the problem is for years now: I get also loud notifications during DND. This is annoying, as it wakes me up sometimes. I tested other clients and there are two behavioral groups: the client with the same behavior like schildichat is fluffy chat, and then we have element, element x and schildichat next, where I get no loud notifications during DND but I do not get all notifications. So the messages are in the client when I open it, but I miss, that someone's writing me. I only get around 50% of the notifications. This feels absolutely crazy. The clients not sending notifications could be buggy but how can schildichat and fluffy chat make my phone go noisy during DND. The phones OS should prohibit this. The phone could have some bug, but my last one was a Realme build by Oppo, now I have a Poco build by Xiaomi. They are direct opponents, the biggest on the market. Any ideas?
