I am currently using beta 11 Mac OS.

When a participant&nbsp;joins or leaves the meeting&nbsp;ZRCUserChangedEventJoinedMeeting & &nbsp;ZRCUserChangedEventLeftMeeting do not fire. Currently the only one that works is&nbsp;ZRCUserChangedEventUserInfoUpdated. Let me know if its just me or a bug.&nbsp;

&nbsp;

Thanks!

Yes, this is a bug in beta 11; more details on the issue are here:

We are pushing out a beta\_12 with the fix.

I have updated to beta 12 and the bug is still present.

When a participant joins or leaves the meeting the event is showing as “None” instead of&nbsp;ZRCUserChangedEventJoinedMeeting or ZRCUserChangedEventLeftMeeting.

When joining/leaving the meeting the event line:

\*r ListParticipantsResult 1 event: None

Can anyone confirm this bug?

Thanks!

It turns out that this is expected behavior. Details are here:

[https://support.zoom.us/hc/en-us/community/posts/360000475186/comments/360000090703](https://devforum.zoom.us/hc/en-us/community/posts/360000475186/comments/360000090703)

Actually, there was a related bug: the person who leaves was still being shown as a participant when the

zCommand Call ListParticipants

command was called. That bug was fixed. However, the issue with&nbsp;ZRCUserChangedEventLeftMeeting and&nbsp;ZRCUserChangedEventUserInfoUpdated turns out to be expected behavior.
