Lightroom classic catalogue not seeing files on NAS.
I have a windows 10 Pc connected to a Synology NAS via ethernet cable.
For a long time this worked great. I would plug the card from my camera into a card reader then import them to the NAS via Lightroom Classic.
Some time ago this stopped working properly. The files went onto the NAS and could be seen in the folder via windows.
For a while I got round this by dragging the files straight to the NAS then synchronising the folder.
Now this doesn't work.
The import may take in a few pictures to the catalogue then appears to do nothing. They are on the NAS but do not appear in the catalogue.
Leaving this overnight makes no difference.
How can I fix this so that the pictures are imported AND appear in the catalogue?
