Interesting, we've used Google Meet quite a lot without issue. But yes do let me know.

The main bit I'm interested in is definitely Tuple, specifically because it has a diagnostic screen (network insights?). When you have a bad experience, I'd love to know what that screen says

Tuple is what I've had the most amount of trouble with. I even contacted Tuple, thinking it was an issue on their end, but they looked at the logs and said it was most likely a VPN connectivity problem, and suggested I try it without Warp enabled, which so far has been seamless. The issues with Google Meet are pretty intermittent and uncommon—it just tends to cut out at rather inconvenient moments. :) The difficult thing about these types of tools is that the bar for what works "well" is really high; even very infrequent connectivity issues are enough to sour one's opinion of the tool.
