Kudos for at least trying to address this, MS should hang their head in shame, this is not the hardest problem to solve these days. If we could do it in 1995 they should be able to do it 30 years later.
I hear this a lot but really, Teams works fine as far as I can tell. Click on meeting, check your hair on camera first, join meeting. It works fine 19 times out of 20 at least.
But for something you use 3-5x a day, that is a noticeable problem every few days. Why it has such an awful reputation.
Teams is an absolute mess.
When I click on something in Teams it shows up in (I'd say) < 300ms most times. I'm sure it could be much faster if done better. However, is that what you mean by "horrendous" or are you seeing 30s freezes or something like that?
And I refuse to switch browsers just to use this disgrace of an app. If it’s supposed to work on the web it should not care which browser I’m accessing it from, otherwise a native app (read: not webview-based) should be made available.
