I use iCloud to sync all my photos across my iPhone, iPad, and Macbook Pro. I use my iPhone to take photos and videos (optimized) and rarely use my iPad to take photos (Full Res) and my Macbook for viewing (Full Res). They are all synced up and updated but the number of photos and videos are inconsistent. MBP 23,512 photos, 632 videos iPad 23,512 photos, 632 videos, 3 items iPhone 23,526 photos, 623 videos How do I sync these up properly? Do I have to go through all my photos and delete the ones I dont want and hopefully it'll get rid of the inconsistency itself? Also, what are those 3 items on my iPad? I noticed when I tried to drag and drop all my photos from within Photos to an external hard drive, 3 items get copied first and they are a few hundred mb in size but have no file extension so I don't I know what they are or what originally were. Any ideas?
