This appears to be a new feature when viewing a Live Stream in Yammer. Curious, my coworker and I produce these events but are now showing up as the "Presenters" since we are added during the scheduling process "using external app or device option." This will most likely lead to viewer confusion. Is this a result of using the Yammer interface to schedule live events as opposed to the old way of using Teams app?
Tested this again and chose "Microsoft Teams option" and when Teams opens I now have the ability to make people Producers or Presenters. Why doesn't the external app option behave the same way?
