It has indeed improved a lot over the last 2 years or so and is now actually quite a mature product, as much as I hate to admit that about an MS product. My biggest gripes with it are its refusal to acknowledge you may be using multiple devices (to this day) and MS’s insistence that a person only do one thing at one time (can’t edit calendar items while checking a chat, for example). Their Linux app is a joke and I’m better off running it from Chrome. The phone app makes the WiFi interface crash constantly and I have to run it off 4G; it is the only app I have this issue with.
Which brings me to another gripe. Teams documentation insists that screen sharing on Linux is not supported, and sure enough you cannot see the option for it while on a call with someone. However if you are in a meeting (with however many people), the option magically appears and works absolutely perfectly.
