When I look at my iPhone photos file, and I compare it to my dropbox, I can see some photos didn’t load. For example I have 15 photos I took at the beach and only 12 of them were loaded onto dropbox. They are all the same type of file. I also have eight videos I took at the beach, and five of them loaded to Dropbox, not the other three. Help? I want to make sure everything is loading so I can delete stuff off of my phone without having to double check that dropbox caught everything.
