Picture files missing from a network drive after Big Sur update
I have a folder on a network drive that I use to store pictures. This folder has a number of sub-folders for organization. After updating to Big Sur, Finder will navigate to the main folder, but the sub-folders and their contents are not showing. I had some photos in the main folder and they were still visible so I tried putting them into a new sub-folder to see if that would make the others visible. Finder will show that sub-folder, but if I leave Finder open for a few minutes, it and it's parent folder will disappear.
If I try accessing the sub-folders from a Windows machine, they are not visible there either.
