It does take a while to figure out zoom timing. Also, smaller groups work better. Early in the lockdown period I was on a 70th birthday zoom with at least 25 people. Absolute chaos and no fun for anyone other than the celebrant. While I was happy for him, I learned that crowded zooms don't work.
My group has been at it for over two years so we have a pretty good rhythm. Also, when someone interrupts with a burning share, we let her finish her thought, but then another person will say, "circling back to where we were, Kathy, what was it you were saying about shopping for a new car?" and we pick it back up. No one's feathers get ruffled.
