Webinar Registration Canceled?

Some people are registering for our event tomorrow and most are getting an email that they are registered and then that their webinar registration is canceled. It is happening right after they register. 

We are not denying registration from other countries. 

Yesterday we turned off the auto approve, because clearly we can't trust Zoom to approve. 

HELP - We can't manage the emails and us registering them by hand (which sometimes doesnt even work)
