I have installed X-Plane 10 on my iPhone with my Apple ID account and some time later on my wife's iPad with her Apple ID account and a different X-Plane Id
When I change the settings to my Apple ID account on the iPad, I can play with the planes I have purchased, but it neither changes the X-Plane id (still different from my iPhone) nor shows the lessons and challenges that I have already passed on my iPhone.
How can I sync X-Plane on my iPhone with the one on the iPad? I tried uninstalling and reinstalling the app on the iPad, but it keeps pulling the app from iCloud and the only info that is update is the purchases I've already made.
