I discovered the PowerPoint as Virtual Background today and I love it! However, it disables mirroring while I use it and I can't figure out how to turn mirroring back on. When I go to Background & Effects in Settings, the "Mirror my video" is greyed out while I am using Powerpoint as Virtual Background. Any help appreciated!
I have confirmed that it is currently not possible to mirror your video while using the Slides as Virtual Background option. I'm very sorry about this inconvenience! I will be asking our documentation team to include this limitation in our article on the feature. I am however thinking this by design, as the mirrored video is only visible to you (meaning participants always receive the non-mirrored version). This could cause you to lean in the wrong direction while sharing and cover a portion of the presentation, as you would not be seeing the same video as the participants.
