I shot some clips today with my new iPhone 11 Pro Max. The clips were recorded as 1920x1088/29.99 fps HD MOV files. When I bring them to Resolve for editing, after timeline creation, clip thumbnails flash and turn red "Media Offline" in the Media Bin, and I also see random Media Offline frames in the timeline itself.
I have provided the diags/log package, a screen capture, and an sample MOV file, to recreate the issue, at the following OneDrive URL:
