I have been working with Apple Support since June 24.  When dragged into the Project timeline it a) comes over black, b) has a red banner message about missing remote data, c) come over in a very very low resolution and d, once in a blue moon come over as expected.  This is the same set up that was connected to my iMac Pro, which worked well.  I moved the DAS to my new Studio and the problems instantly began.  I exported several photos to my iCloud Desktop and I could import them into FCP flawlessly.  When I moved those same photos onto my DAS, I could choose them to import, but they would not import.  Has anyone else experienced this?
