I recently switched systems from an old iMac and direct attached external drive to a new 16" MBP and QNAP NAS. I am using this for both photography and video. I have some weird behavior on the Lightroom side that I'd like to understand. In general working with the NAS has been more troublesome than the direct attached drive.
I have Lightroom preferences set up as follows
"Store a copy of all smart previews locally on Macintosh HD" is checked
"Store a copy of all originals at the specified location" is checked
Storage location for originals is a folder on my NAS "Volumes/media/Lightroom"
Here's the issue. When I try and import using the "Connected Devices" option I get a failure. If I use the "Browse" option, I can browse to the contents of the card and successfully import. This was not an issue with the direct attached external device.
