I went from a iPhone 11 to a iPhone 16 Pro a few months ago. I backed up photos to Dropbox before I moved everything to the new phone. Had issues with the new phone and Apple had me do a full factory reset, and then I was only able to download certain (minimal) apps from my cloud, to prevent the new phone from picking up anything old that might have caused the issues. This shouldn't affect my Dropbox app, since that is a separate cloud. But now when I back up photos, it is scanning my ENTIRE library of photos, which is many years worth, it seems, and it seems to want to download all of these photos, most of which are already in my Dropbox. I went to settings to see if selecting "Back up/New photos only" would solve this issue, but it only identifies new photos as of today, not the past couple of months since I got this phone. But then I looked at what's in my Camera Uploads folder, and there are photos from as recent as early December, but not current. With my old phone, Dropbox would only grab the new photos since last upload. So what am I doing wrong here?
