My organisation has two Teams-domains for the users - in one I have full rights, i.e., can create channels etc, and in the other I am a guest (another usergroup has full rights in this domain). For each domain I have a distinct account, and I can normally easily switch between them.
Since last week I am unable to switch between the two accounts on Linux. When selecting the account for the guest-domain, the Teams client restarts, but with the same account. However, sometimes it briefly starts with the account I want to switch to before restarting in the other account.
I also have a Windows machine where everything works flawlessly. The web-client under Linux works as well. Therefore, I think it is a problem with the client. I tried reinstalling, with no success.
Elementary OS 5.1 (based on Ubuntu 18.04) with Teams 1.4.00.7556 (64-Bit).
