Dark screen shows for front and back camera on iPhone 15 Pro Max
iphone 15 pro max used as a web cam on Zoom and facetime, since macOS 15.3 only a dark screen shows for the front and back cameras, also when plugged in with usb-c cable. Todays update of macOS 17.3.1 and similar update on iphone did nothing to correct this. Air drop works both ways, and the iPhone works as camera with third party software Elgato. Are other people having this bug issue? macOS 15.2 did not have this bug.
