Sending Zoom links

[Lynne726]

When I open zoom immediately see the time is ticking for that meeting. I try and send out a link for a participant and all I'm getting is an error message. The link either ends up in my Gmail outbox or it gets to the participant about 10 or 15 minutes after the meeting should have started. I need to find out why this is happening and how to avoid it. This is how it happened on my android kindle tablet here.

On my computer, Zoom does not open for more than one meeting. Even if one meeting were 1st thing in the morning and one were late in the afternoon.  I need to know how to fix both these issues.
