Dear KateG ,
Thank you for your response. I am aware of the solution you mention (Share Screen), but unfortunately, it is causing issues, as sometimes popups from other software appear. Therefore, the "Share Application" option resolves that issue but creates confusion for my speakers, as they cannot share the slide show view. Microsoft Teams does not have this problem. With Microsoft Teams, when you "Share Application" (PowerPoint) while in editing view and then switch to slide show, everything works smoothly.
Would it be possible to address this important issue in a future update?
