I am experiencing the same frustrating problem that many have posted about -- but for which Zoom has not supplied a good answer: I use and have always used my PMI. But for the last several weeks, attendees to meetings for which I have send out my PMI arrive and get either a "Waiting for Host" or a "Meeting in Progress" message, while am waiting in the room. I now have to regularly -- though not all of the time -- send a fresh link from the meeting in progress. This makes no sense. It is the same link. Has anyone found a fix? Has Zoom supplied an answer to what is going on?
