I'm using an iPhone with iOS 9.3.1. This is my first time running PhotoBackup.
Everything seems to works fine via SSH on a remote Linux machine. But the app only syncs 47 photo files, although I have thousands of them on my iPhone. I tried to delete the .photobackup file and launch the sync again, no luck. I even got to a point where it would sync only 1 file. Then 47 again, but only 47. I selected "all" in "select photos and videos to backup" settings. I also tried to disable the "skip photos and videos to backup".
Any idea? Your app looks great otherwise ;-)
