I am a member of multiple teams where I have the same username/email/password. When starting Mattermost and having logged in, I see my teams of which I have to choose one. This step seems really unnecessary, because this is why I logged in in the first place.
But now here is the issue: I can switch between the teams by choosing “Switch to” from the menu, but when I switch using the tabs (in the top of the window), I still see the login window. No matter what I do, they won’t disappear. Only after a Ctrl-R, I get the team chooser again.
Also found out that the choice I make in the team chooser, loads that team in the active tab. When clicking the tabs, it shows me the team of my last choice, and not the team that is mentioned on the tab. This makes this tab list completely unusable.
