Teams on the Mac is a UX disaster. Start the application, you get a Teams logo. Then it switches to a large white window, that can persist for up to 40seconds (100 mb fibre). No indication of what the app is doing. Downloading a full app every time? In some meetings I have lost the ability to access the chat. When trying to access recorded videos that I get a shared link to I end up with a login window that refuses to acknowledge any account (maybe I have no access, but that isn’t what it tells me). The resources section, files etc, is confusing to the point of being useless and old videos just tell me a token has expired.

I really do hate the lack of native notifications. It's ridiculous

Teams on my Mac has this wonderful feature where the notifications render as a completely white rectangle until I mouseover, and then it finally renders the content.

What exactly does the teams implementation need to do that cannot be achieved with the Mac notifications?

When I get a notification all I want to do is be able to click it or dismiss it. But teams loves to appear on the wrong screen, behind windows, or just not show up at all. That combined with the questionable design choices of the UI, I have missed calls because I heard the sound but couldn't find the alert for it.

Sadly this is likely never to change since Microsoft does the exact same thing for Outlook, which is why I refuse to use it and just stick with native apps for work.

What do the custom teams notifications give you that isn't provided by the native mac notification system?
