iOS: Event Ended Issue When Using MeetingSDK WaitingRoom

Meeting SDK
1

iOS MeetingSDK 5.12.2
zoom-sdk-ios-5.12.2.4959

When a user joins a meeting after being allowed in from the meeting room, the following occurs:

For the Android, WebSDK: WaitingRoom => Permission => JoinMeeting
For the iOS SDK: WaitingRoom => Permisson => (Event: onMeetingEnded, MobileRTCMeetingEndReason.selfLeave) => JoinMeeting
(zoom-sdk-ios-5.12.2.4959)

Even though the participant successfully enters the room, the log shows an Event Ended message as soon as the participant joins the room.
Is there a way to fix this issue?

Hi @uehara.masaki , thanks for the post! I followed the steps and tried to reproduce the problem, but onMeetingEndedReason is never reached from my side. Are you running the sample app in zoom-sdk-ios-5.12.2.4959 or running your own app? Also, can you please show me the logs containing the error? Thank you.

Hi, Qing.
thank you for your reply.
We produce original application using ZoomSDK.
and use the waiting room.

It is the cord of the crank output part.
event: onMeetingEndedReason

func onMeetingEndedReason(_ reason: MobileRTCMeetingEndReason) {
    if (reason == MobileRTCMeetingEndReason.selfLeave) {
        print("##### User leaves meeting. #####")
    } else {
        print("##### Other reason. #####")
    }

I list log.
In a timing of Accept permission, “##### the user leaves the meeting. #####” is output in onMeetingEndedReason.

Join Meeting.

Hi @uehara.masaki , thanks for providing the logs. I can see from the logs that onMeetingEndedReason is reached before the user joins the meeting. However, I still cannot reproduce the problem since I don’t have the codes you are building. I tried in the the sample app again, and onMeetingEndedReason is never reached when a user joins a meeting from waiting room.

Can you please check the codes to see if you call leaveMeeting somewhere like in timeout handling? Also, my suggestion is to try and compare the sample app for joining a meeting, and please feel free to post any updates there if you can find a way to reproduce the problem, thank you.
