I use zoom to setup meetings with my clients. I used to be able to send one link and the client could reuse it for the future meetings. 
since I bought a new computer that has been impossible. My clients said when they try to reuse the link, they get a massage saying, link is expired. I have to send a new link every time. 
I have 4 sessions with each client. 

Hi, I have been using zoom since the very beginning and been doing many zoom calls. Lately, my own live picture, is becoming whitish, like a ghost. Then I have to turn it off and on again and then it works for a while. It is not professional and I am not using any background. Previously it has worked. Where should I start to find the correction?

I did add the background and thought that might have caused it but have removed it again! Thanks for your input.

I was a guest of a meeting, my daughter was the host.  She gave me permission to record her online baby shower.  After the meeting was over, it said it was converting.  It asked where I wanted to save the recording.  So I directed it to the 😧 drive where I put in a zip drive.  It said I didn't have permission to save there so I clicked on skip so I could go back.  Then it went away and I can't find out where it went.  Did I loose the shower forever it was on 2/25 at 6 pm AZ time.

I have a series of 8 weekly meetings set with required registration which I thought would cover all 8 sessions with a one time registration but when the registration populated on Zoom it set up registration for all 8 sessions separately. What should I do if participants accidentally registered for only the first session or first couple of sessions but wanted to attend all sessions ?
