Wouldn't finish processing photos – The Roll - Automatically organize and find the best photos in your camera roll Review

I tried to have this process all the photos on my iPad Air 2 and iPhone 5s and it wouldn't finish my library of 3200 images after a whole week of trying with numerous app crashes and device restarts. It only made it to 3100 or so and wouldn't progress any further. Please fix the bug causing the failure in processing all of the photos.
