As host, some but not all participants can't see my chat
In a Zoom meeting I hosted, towards the end of the meeting, several, but not all participants could no longer see my chat. This wasn't happening earlier in the session, so I don't know what changed. I had used the break-out room function several times during the session and some participants came and left and re-entered the meeting, but that is all in terms of disruptions. To resolve the problem, a participant who could see the chat copied and re-pasted it into the chat for everyone to see it. As host, this is far from ideal. It is the send time this has happened. I'd appreciate help resolving the issue.
