Thanks for the update.
A couple of quick thoughts on an initial test.
Connect over the LAN gave the ‘Have to use the same version’ error, even though PRO/Performer were the same. Switched the Performer over a tethered phone and then connected fine (no other changes)
On Windows the original aspect ratio of the webcam is ignored (haven’t checked a Cubase Video) - Logitech 920 is 16:9 but is cropped to 4:3 in PRO. Mac seems fine and keeps 16:9. Not a showstopper but a bit ugly.
