I just created my first account on signal, using signal-cli (since I don't have iphone or android). this works so far, i can send and receive messages. But to join a v2 group, it seems like I have to create/update my profile with a name and an avatar. signal-cli provides the command updateProfile, which I used, without getting any error. When I checked under .local/share/signal-cli/data/<my_number>, I see the name which I entered. But my contacts don't see neither my name nor my avatar. also on my linked device Signal Desktop I don't see them. Executing updateAccount with signal-cli doesn't help. Any suggestions?
