Today I took a picture and a video on my iPhone 15. On the "Photos" tab in the Dropbox app, the recently taken photo shows up, but the video does not, even when I have the dropdown set to "All". (And several other videos I took a few days ago don't show up either.) And since the app can't see them, it's not syncing them to the cloud.
This used to work correctly, where every photo and video I took would be synced to Camera Uploads. But then on June 25 my iPhone 15 got stolen so I replaced it with another iPhone 15, re-installed Dropbox, and now any videos that I take don't show up in the Photos tab. App version is 484.2.4 and I don't see anything under Settings that could be relevant here.
(The big black rectangle in the middle is just to cover some photos that showed other people's faces.)
