App is broke

This is app is currently broken on my iPad Pro. Will not launch. This occurred after latest update.

On my iPhone, I had to redown load all my books that I was reading.

The sync does not work between iPhone and my iPad when the program did work - version before this failed one. (At least from my point of view.)
