Oh interesting, I could say all of these same points for Teams.

Being signed out on Teams leads to a really slim banner at the top (of the already messy UI) that tells me to sign in again, the strip is even grey... the only reason I notice I am signed out at all is because I have notifications on my phone that aren't reflected in the Teams UI. This is a consequence of my IT department having short sessions, but the fact that this is how Teams displays it- is a fragrantly terrible UX.

The more annoying one is when my phone is signed out I just stop getting push notifications. There's no indication that I need to sign in again or anything. I think Slack would have the same issue with short session times to be honest, unless they send you a push notification every time your credentials expire which is also frustrating.

Teams working in Firefox is relatively recent, afaik it still doesn't work in Safari. I think I specifically had to install Chrome a few times to join job interviews that were conducted on Teams as Firefox definitely was not supported a year ago.
