Add User Tod private Channel on Android


i have recently installed a RC-Instance on Ubuntu 18.04 via snap.I’m new to I tested the iOS app and could not find any problems. But with the Android app, I can not add users to an existing (private) channel. Unlike the iOS app, the “plus” button is missing in the user overview. Also, I can not join a public channel because I can not find the “Join” button in the Android app.

Is this a normal behavior of the Android app?

Thank, you!

We created Teams for each client, to include our staff and client’s staff. It was actually more trouble than it was worth, and so have abandoned it.
