Yea… Microsoft has a history of doing this a lot… their “concession” to being a large software developer is that each version of an app seems to have an entirely different team that develops independently from the other platform versions (the best you can say is that they occasionally borrow good features from one another).
I recently got forcefully switched to “New Teams” at work which is a strict downgrade and doesn’t support half the shit the browser app (which, as a reminder, is a weird Frankenstein of calendar and email) supports. It also absolutely bombards users with unnecessary notifications that need to be individually muted.
Never have I appreciated Google more than when I was forced from GSuite to SharePoint, Teams, Outlook, Visio, etc…
