This is a neat idea :) managed to register okay and connect it to my Steemit account after reading the comments here.

Now I'm trying to make a photo post. Took a bit to work out how to add tags, but got that sorted. Now though, it gives me an error when trying to post. Says creating post is impossible, Cloudinary API error "Invalid URL for upload".

Eta. Nevermind, I pressed the back arrow at the top of the create post page to return to trending. It showed the Login button in the corner, so I logged in again and started the post from scratch and it worked this time.

When I go to my profile in the app it shows the one photo post, but says I have 2 photos in the text above the post list/grid.
