All my RAW files are stored on my Synology NAS.
I use LrC (10.4) and PS 2021 (22.5.1) on my MAC running Big Sur (11.6).
My LrC catalog files are on my MAC's local hard disk.
When editing pictures in LrC, and then moving to PS to edit a COPY, when closing PS and doing "SAVE", I don't find the PS picture in LrC... I have to manually import this picture in LrC.
All works well when I do this with a picture which is stored on my MAC's local hard disk !
Anybody out there who can help ?
