What happened?

This app has been great and invaluable until today. I had downloaded the free version and then purchased the upgrade in the app weeks ago. All worked well until an update of the app yesterday and my iPhone updated to 9.3 last night. Now the app is almost useless. Cant choose sides anymore and many screens are just blank. Restarting doesnt help. Please fix this previously great app!
