When I use the Dropbox iOS app to upload photos, the app is not seeing all of my photos. For example, I have 3000+ photos in my "All Photos" album, and Dropbox is only seeing 255 of them. I double checked and know that the missing photos are not the "thumbnailed" ones already uploaded to iCloud Photo Library. Dropbox isn't even seeing the full resolution originals that are on my phone.
