I have the same problem now (I did not have this problem in version 16)
- When I add a video recording unit like my iPhone or Facetime camera, nothing can be seen in the in preview, no video image, no placelines in the preview widow, only a short red line in the left corner. What could this be?
- also I can not add an IOS Camera, nothing shows, even when I refresh or reconnect devices.
I have the newest v/32.0.1. This dysfunction also existed for me in version 30.
