This is a very common workflow for me, except I was using Teams on a Mac. And thanks to some update there are now two non-working versions of Teams installed ("Teams" and "Teams new" or some equally tacky naming). Luckily I have a Linux laptop next to it that can run it in-browser.

I would love to know what Microsoft thinks the purpose of the standalone app is, when it is both slower and less reliable.

The "great" part about the Office desktop apps is that they're written in electron, so it's already essentially a web app but somehow worse.
