Have they fixed the problem where if you have only a few participants, and one is on a connection that is I a separate region from the others, that participant will show the symptoms of the queue they are on being stuffed instead of flushed, and e.g have audio and video freezes that never catch up, and not be able to see screen shares even when video is off?

This was an issue for much of last year. In larger calls this didn't happen, but it made teams a painful waste of time and energy for actual team communication, rather than big announcements. Hangouts/meet and zoom both work fine in the situations I'm thinking of.
