I have synology ds215j and two HTC One M7 (my and my wife). First i installed DS Cloud to the phone of my wife. After installation i created the shared folder on ds215j. Next i configure DS Cloud on the phone of wife to sync the folder DCIM with the shared folder on the cloud. Sync works fine, BUT when all photos was syncronized with cloud - they disappeared from gallery at the phone. Standart phone gallery doesn't able to find photos at the standart folder DCIM. I try to connect the phone to my computer and i see that all photos in the folder DCIM, but gallery can't find them...
So after that i decide to check this issue on my phone. And also after sync there is no photos on the gallery at my phone!

Any help will be apprecited.

I didn't find the right solution from the Internet.
