Yesterday I started with a Oneplus 5t with UT. I tried to videocall with my mother on Signal UT. We could talk and I could see her, but see couldn't see me.
I also have family abroad, so it is a pretty important function for me.

Also do I have a very big local community here on Signal (>500p, 20 groups and also more specific topicgroups non-local). It is important for me to put off sound-notifications for some groups and not for others. I couldn't find how to do that. Is this already somehow possible?
