Been using Teams for 6 months, it's awful. Being asked to log into another Teams instance, for example, results in baffling issues; I had to switch to the web version and that only works sometimes. Turn off a VPN? Be prepared to suddenly, without warning, have a 10-15 minute period where people are messaging you and you don't get any of them. (I am talking about Teams instances that do not depend on you being behind a VPN, more on THOSE after) Video conferences are terrible. I keep getting invites without the Teams URL attached because of UI issues, and worse, there are situations where I can't even access the URL I am given. Low quality Enterprise security teams often ruin Teams installs. For some customers I work with, I am not even able to upload an image to a group chat. (Not a meme mind you; screen shots). "Sure that's the price of a locked down / professional service" you may say, but for some obscene reason, I am able to use Giphy in these chats. And many other miscellaneous issues (degraded experience on Firefox, authentication headaches w/ AD Azure, etc..) As far as I am concerned, this is MSFT's fault since they sold a product that can be configured into complete uselessness for its purpose (sharing information). (Disclaimer: I own MSFT stock and generally like their direction but the execution for this and Azure DevOps is seriously lacking)
