Hi all,
i dont think that apple will fix this issue soon, so i started debugging the process of ios sync & photos.
Photos shows 45.152 pictures linked to my library (but stored externally on SD/USB), which is fine.
When a sync is started, the AMP processes seems to triggers photos and directory "iPod Photo Cache" is created (withinin library). All photos of "iPod Photo Cache" are correctly synced to iOS, but this is only a small size (1.326 pictures of 45.152).
I am still investigating, why photos just notices this some pictures.
Using a new photos library using a different user-profile on macosx worked fine (using just "some" pictures).
Enabling debug mode i can see that only 1326 pictures are captured....:
