@kanata.koyama ,

Thank you for posting in the Zoom Developer Forum. Sorry for not getting back to you sooner. Is this behavior still an issue for you?

thank you for reply!
yes, it’s still an issue for me…


Have you identified the cases in which the user gets stuck in the waiting room? Does this happen on the first test, or do you only see this behavior when attempting to join the second or third time?
