Waiting Room disappears mid-meeting and I can't see people waiting

[EmilyKeene]

When hosting a meeting, my Waiting Room disappears mid-meeting and I don 't get notifications and I can't see people waiting (I know they are in "a" waiting room because they either text another participant or put it in Meetup chat). I can't bring up a waiting room, and they don't seem to be able to get in even if I've disabled the waiting room. I haven't limited the number of participants (there would be twenty at most) and I have a paid membership. Is something timing out at a certain time after the start time?
