Version 1.6.24 - Some rooms / conversations switched to "Silent Notifications".

### Steps to reproduce

1. In a room or private direct conversation
2. Send a message
3. When recipient responds, it is "silent" (used to be Noisy)

PS: This was not happening in 1.6.18 (as we didn't upgrade to 1.6.20, due to microphone bug)

We tried to see everywhere if we can switch a room from "silent notification" to "noisy notification", but there is absolutely no toggle anywhere. In the app, if we go notifications, everything is correct. And if we go into Android notification settings, we can see that some of the "rooms" and "conversation" are randomly marked "Silent notifications". If we click them, and change silent on top to default, it doesn't change it to Noisy Notification. Also, if we do "default", in sound, it makes us choose a bell for ringing VS a notifications sound.

Please look into this bug, as we will have to once again downgrade back to ver 1.6.18.

### Outcome

#### What did you expect?
I expected my phone to create the default sound

#### What happened instead?
No sound at all :(
