I ran into that issue about a year ago as well. I also had Outlook in the mix because I was creating the series from the Outlook plugin. I would go and edit a single instance of the series, but then users started to report some MS errors when they went to join the meetings. I then tried to create them from my account on BlueJeans but could not manage or edit a single instance. This is an excellent question that I hope BlueJeans reviews. Keep us posted if you find a resolution!!
This is Ashwin from BlueJeans support team. Currently, this behavior is as per the design i.e., you will not be able to edit a single meeting from a series when scheduled from web account. Our engineering team is aware of this and are working on a fix.
The workaround for this would be scheduling a recurrence from Outlook. When you do so, you will have a an ability to edit or delete a single meeting.
On a recurring meeting that is on the calendar for today (this week) it gives me choice of CANCEL MEETING or CANCEL SERIES - but in future weeks it only allows me to CANCEL SERIES.
The inability to individually shift specific instances is a huge problem - why have recurring meetings if they are unalterable.
Is there a workaround (other than separate meetings)?
