I’ve just discovered that sending a photo directly from my mobile phone to create a post does not work via a WordPress app. Many apologies for the bomb sent directly before this post. I tried this a year or so ago, and it didn’t work then. I must be congratulated for always being the optimist if nothing else.
I’ve also learned to save a photo in medium, and not original mode.
