I turned the sync on and put some pictures in hidden album. I was not connected to internet.
somedays later, when I connected to internet, i lost all the pictures from beginning in the hidden folder. yesterday again I connected to internet and many old hidden pictures were visible in sync on mode in gallery. but I am not getting my those recently added pictures. neither on cloud. they are extremely important. is there any hope? :(
