As far as I can tell, all my photos are uploaded, and the counts on my Mac and iPhone both match, 18770 photos, 158 videos. Everything is there in both locations. Yet my phone says "Uploading 1 Photo" and never seems to get around to finishing. Anyone know why this happens? This isn't the first time either. iPhone 6, iOS 9.2 Running OS X 10.11.2 on the Mac.
