It seems that IMeetingUIElemConfiguration.HideMeetingInfoOnMeetingUI(bool bHide) is no longer working in Windows SDK v5.2.42037.1112, under share, control/more, meeting info is there, we would like to know how to turn off this meetinginfo, in previous version 5.0…0616, it worked fine.
We do not yet have an exact date for the next SDK release. Historically we have aimed for a release cadence of every 2-3 months, which typically has changed if there are urgent bug fixes needed. This is not a guarantee of when the next release will be published, but may help to give you a rough idea.
