Seeing same person in 3 squares, and occasionally all blacked out except names.

I host 5 AA Meetings a week and they all work fine except one. It's in the USA on Thursday 1.30 EST. The screen can be blurred and a pink colour in every picture. or It can be completely blacked out in every picture except for the names of the participants. or I can see three or four videos of the same person in each square. The other participants have no trouble with this Meeting. When I sign into this group I get told having trouble connecting you, please join with your browser. Help please
