In Zoom meeting
From Participant's account, he/she  clicked  "Join Session" or "Join meeting" or meeting link before the scheduled time but showing that the meeting has not started.
but when checked with host, 
he joined the meeting.

they were not able to connect on Zoom when both the participant and coach joined the session.
any suggestions?

Hi Everyone,

I have an Acer Nitro 5 and a Dell Inspiron 16. I have kept my zoom updated on both. 

Is it possible that someone could use the back office of zoom to trigger a crash report prompt to a participant or do something to cause a participants zoom to suddenly stop working for no reason? It's been happening to me frequently in my evening meeting. I have a very high end stable computer. I haven't done anything wrong to aggravate anyone during this time either but it's possible a host could be doing this out of hostility. I usually just hit "Don't send" and it just hiccups and puts me back into the meeting like I rejoined. But sometimes it happens when I am screen-sharing. I was just wondering if there is anything I can do to prevent this from happening further? All solution-based tips are welcome.

I will post a shot of the error I receive if it ever happens again.

Thanks in advance.

I run a support group over Zoom.

Because meetings run two hours, I updated to the Pro plan so as not to be restricted to the 40 minute limit of the free plan.

However attendance has reached 91 and rising all the time.

I need to plan for larger capacity now.

Am I right in saying it will cost just under $50 per month to allow more than 100 participants with "Large Meetings Add On"?

I only need one licence as the support group facilitator, not several.

There's no cheaper way to have more participants than 100 for a single licence?
