Support ticket

I'm having the same problem. Did you figure out the problem?

They have been no help at all.

Greetings, when we’re hosting a webinar the option to lock the meeting is no longer there. Is there a way for you to add that feature back? Thank you, Veneka 

That sounds really frustrating. If your ticket was closed without resolving the issue, you might try reopening it or submitting a new one through the support portal. If possible, also check if your account has access to live chat or priority support depending on your plan.
