I didn’t think the initial initZoom was right, so I did the init again.

How To Reproduce

  2. joinMeetingWithJoinParam (userName, meetingNumber, password)
  3. show UIAlertController
  4. crash

Any update on this crash?

We also experience a similar crash. It occurs after we tap the agree button on the disclaimer. So far, this crash seems to only occur when we’re in the waiting room and showing another view controller on top of zoom meeting screen.

I attached the stack trace below
