Fail to join the meeting, No permission

@tommy Thanks for your reply in Email. I am using a developer account for JWT app token and you feel there is no issue with that account. Zoom also recommends using a PRO or a higher account for creating JWT app token and we can use it but there is definitely some issue and I feel it’s related to the number of users who joined using web SDK. I do see that it’s an issue with PRO accounts to Rate limits on joining meetings/webinars? so I feel that upgrading to PRO may not solve this issue. If you can provide me with the maximum number of attendees who can Join from the developer account and PRO account then it will be really helpful (If there is more bandwidth in PRO account we will definitely upgrade to PRO). I have also analyzed this issue further and below are the outcomes of it

  1. I was getting No permission. error in the ongoing webinar before few days. I was successfully able to join other concurrent meeting hosted by different Zoom account which was using JWT app so the limit was not in applied on application account which was used to create JWT app tokens
  2. I was able to join in same webinar using a different JWT app token (I was only attendee using this other platform account and in main account there were many attendees so it was blocking all new users with No permission. error)

The overall outcome of the above two points is there are limits based on the account being used for creating JWT app token and the number of attendees in the webinar. I would like to know those limits in the developer account and PRO account. Can you please suggest solutions to prevent this issue?
