What is popping up? Toast notifications?
1) looks terrible
2) does not behave like a standard OS notification so you can't swipe on the trackpad to dismiss it nor does it appear on the lockscreen (if your system is configured to display notifications on it)
3) is an always-open window (though invisible when not in use) but it still appears in the "window" menu and you can focus on it (seriously WTF? why not just create the window when a notification is displayed and destroy it right after)
4) takes up a lot more space while not delivering any more information than what a standard system notification would deliver
This is an incompetence problem, just like all the other shortcomings of Teams.
Of my complaints I might have with Teams, this is the one that raises the temperature of my blood a bit every time I see it. The fact that you can focus on it particularly pisses me off because when I Cmd-Tab to the Teams main window there is nothing in that window that appears to have focus. You have to click on the main window before ti becomes useful. ::eye_roll::
