I just tried to setup up Synology Drive (latest version as of the time of this post) the same way and have the same problem. Just to be clear for everyone. All my catalog files are on my local system on an SSD that is directly attached to the computer, and I am not looking to move that off to my NAS or the cloud. Even with 2.5 GB ethernet, it is not fast enough. I want to ensure I have copies of my catalog files and make it easier to move between a Desktop and a Laptop when I am working with a catalog. Now I know this works on Mac, and there are no limitations. I request everyone who sees this or has posted to this thread to upvote so we can get Adobe to see it and respond. Also, request an enhancement with Synology to see if they can support an exception for folders and backup even if Lightroom is not creating folders correctly. Clearly, Adobe is doing this for a reason, and it would be good to understand why. As a highly technical individual with a stronger understanding of systems and networks, I see no reason they are doing this or, at the minimum, giving people the option.
