**Description**  
One of our clients can’t join a zoom meeting on his device. Checking the logs, success or error callback for ZoomMtg.join is not called at all. But please note that the `inMeetingServiceListener`’s “onMeetingStatus” and “onUserIsInWaitingRoom” event was properly called.

Could you suggest a way to fix this issue? Below are some unusual console logs encountered.
