In the past, when I had mirror video on my video continued to be mirrored when I flipped my camera. Now the mirror view only works when I don’t flip the camera. This is a big problem; I teach music and I need to see myself in mirror view both when I’m looking at my face while teaching and when I have to flip the camera to show my hands playing the piano for example.
In short, mirroring my camera works great when I'm looking at myself teaching but whenever I have to flip my camera (for example to show my hands executing a piano part) it looks completely backwards. In the past, this was never an issue; flipping the camera still showed an image the same way I see it in real life.
