Zoom.join() hanging for combination of 'Allow participants to join anytime' and 'Waiting room' option

Description
Hello Team,

We recently running into an issue that guest will not be able to join, just showing black screen.

In a recurrence meeting which has ‘Allow participants to join anytime’ set true, ‘Waiting room’ unchecked. Modify a single occurrence to turn off ‘Allow participants to join anytime’, turn on ‘Waiting room’.

Then by joining this modified meeting, guest get a black screen.

Error
Nothing is returned, waiting for success/error callback forever

Which version?
1.8.5

To Reproduce(If applicable)
Steps to reproduce the behavior:

  1. Create a recurrence meeting which has ‘Allow participants to join anytime’ set true, ‘Waiting room’ set false.
  2. Modify a single occurrence to turn off ‘Allow participants to join anytime’, turn on ‘Waiting room’.
  3. Don’t start the meeting
  4. Let guest user join the meeting
  5. Guest will see black screen

Screenshots
If applicable, add screenshots to help explain your problem.

Device (please complete the following information):

  • Device: MBP
  • OS: macOS Mojave
  • Browser: Chrome

Additional context
ZoomMtg.init() is working fine which calls success callback that calls join()
ZoomMtg.join() never calls back to success() nor error() callback

Hey @Wenbo,

Thank you for reaching out to the Zoom Developer Forum. Are you able to share the code you’re using to init and join the meeting? I’ll use that to reproduce the issue on my end.

Thanks,
Max
