Has this happened to anyone. I had a meeting set up and found no one could get into the meeting because Zoom had inadvertently, without informing me, changed the passcode and that passcode did not work.
This happened to me, which may be what you experienced. I thought I could use my PMI for different recurring meetings I set up and incorrectly thought I could change the passcode for one of the new meetings. When I changed the passcode, thinking I did it for just that one meeting with its own unique title, to my dismay I had changed the passcode for all recurring meetings that used the PMI. I discovered it when members couldn't join the other meetings in the future because their passcode no longer worked.
