Disklavier

I'm new to this forum so I apologize if my question  has been answered. 

When I start my Apple IOS Disklavier Mark IV App. I get a message something like:
App out of date, may not run on future releases, tell your provider. 

I have the latest release from the App Store. V 1.2.2

Does anyone know what Yamaha is doing about this?
