Q: Art mode upload photo button disappeared with new iOS app update?

[u/RajRaizada]

Until very recently, a good way to upload your own photos to the FrameTV via the art mode tab of the SmartThings app was via this button, in the lower-right corner of the app.
(Image with the helpfully added arrow from here: https://www.tidbitsandtwine.com/how-to-add-art-to-samsung-frame-tv/#h-3-tap-the-photo-icon

However, recently the iOS SmartThings app seems to have updated, and that button is no longer present. The second uploaded picture is a screenshot of that part of the screen on my iPhone. The little picture icon with a + sign on it seems to have gone.

Does this mean that this "Upload a photo" functionality has been removed? I hope not!

Any help gratefully appreciated!
