Also no idea what he is talking about, I have 4 work accounts in Teams. Ever since they rebuilt their frontend to the “New Teams” multiple accounts have been working just fine.

In the past I had multiple Team instances as PWA for different work accounts, nowadays it’s all in one app and works pretty good.

Not to defend Teams, it’s total shit, a lot of shit straight up doesn’t work half of the time, including important shit like notifications for new messages and content. But it has come a long way from the days including any image in chat would crash Teams for all participants. It isn’t perfect and the amount of resources it used to do what it does is awful, but compared to most modern apps it’s pretty good.

Just don’t tell a Teams dev Microsoft Messenger did 99% of the same stuff and ran super fast on a Pentium 3 333mhz with 64MB of ram, they’ll cry and you’ll be called out for being a bully.
