So you think I didn't read your comment because you said "Nope, nope, nope" and I quite literally provided you with instructions on how to do it? That feels incoherent.

> To check messages in a client Teams I just have to RELOAD THE WHOLE APPLICATION

lol Where are you reading "reload the whole application"? It's literally a dropdown menu in the Teams application. It switches the tenant.

> That's a weee bit harder than hitting command-2...

Oh my god, clicking a single dropdown isn't a "weee bit harder". You're acting psychotic about this.
