Hi,
Perhaps I wasn't clear enough. I am only using the native Photos app on my iPhone 11 Pro Max which is running iOS 14.3. When I view a photo in Photos, if I slide the photo up with my finger, a small text box appears beneath it reading "Add a Caption." In this box I can type a caption. In the future, when I slide up on that photo in the Photos app, the caption I added appears beneath it.
On my desktop computer I can visit https://www.icloud.com/photos/ and see my iPhone photos synced there. These photos all have a small line of text underneath them labelled "Untitled." The captions I add on my iPhone are *not* syncing to this line under the corresponding photos on iCloud.
What I want to know is: Should such syncing be happening? It seems obvious that it should happen, but perhaps this feature was not implemented by Apple.
Thanks,
Tom
