Great app but currently broken – Diptic Review

I suspect iOS change is the problem. After selecting images to used step, the icons for the images no longer appear in the work area so you cannot proceed to the next step. I have rebooted and reinstalled, it’s still broken. ————— Review for when it works: I often create a animated 2 x 3 collage of photos for friends and publish it. Very, very nice. After publishing, I need to return to to the last animated collage and substitute a photo or two, keeping aspect ratio, frames and all other settings so I can publish a new customized animated video. Please, please add this capability!
Review by is the nickname taken too on Diptic.
