I am trying to use Android sync on my lollipop s5. I cannot add a sync folder to my device storage. When I try and link an existing folder, it gives me the warning that the directory isn't empty, and won't let me past that dialog box when I click ok. When I try and add an empty folder to sync to, it allows it, but the folder doesn't show up in the list of sync folders. I had no issues with 1.4
