A2 Lite running Pie. Google Cardboard Camera Viewer (GCCV) will not recognize QR code from the VR case. In fact, it will not recognize any cardboard camera viewer code at all. I installed several QR viewers (and they all work), but the GCCV will still not work. Within the app "sites in VR", you can select the right viewer (Zeiss VR One Plus) and even custom make your own (and it works correctly, but ONLY in this app). GCCV then shows the custom viewer instead of default, but it really is the default viewer. Anyone have a fix for this?
