Issue connecting to a oom meeting with the Zoom joining link

[pensions4p]

Hello, 

I host live events using Zoom Meetings and we are incurring issues throughout the live events that registrants and even event speakers can't access the Zoom event via the link they received from Zoom after they registered. The receive a message along the lines of 'You need to register for this event' in which case they are registering again on the spot. I can see their registration emails coming through but when I go to the Meeting in Zoom, there are no new registrations and I have to approve them all.

I am also finding Meetings that don't require registration is also an issue for my internal team to join. 

Any ideas, help, suggestions gratefully rec'd!

Thanks.
