I have many photos in the "Photos" app of my ipad and I spent hours organizing them in Albums using the ipad.
Today I performed an itunes sync of a folder in my PC containing additional photos. After that, various of the Albums I had previously created in my ipad became empty (the photos still are in the ipad but the Albums are empty).
Feedbacks on why this happened would be greatly appreciated.
Thank you in advance!
