My team had a meeting with Github sales and product a few weeks back. After I secured a booking of the special Teams-capable meeting room and arrived 10 minutes early to make sure everything was set up in time, we spent the first 10 minutes of the 30 minute meeting with 2 people from Github unable to join. At that point I generated a Google meet link, put it in the email thread and we were up and running a minute later.

I've found Meet to just work about 98% of the time. My biggest complaint is the framerate. I'm not sure what it actually is but it feels like 15fps.
