Can’t restore on new device – Flight Pilot Simulator 3D! Review

I love this game and made quite some progress! But now on my new device it tells me I need to log into Game Center to restore my purchases. I AM LOGGED IN!!! But the game isn’t registering it... I don’t know what to do? I have tried uninstalling and reinstalling but it’s still not recognizing that I’m already logged in. Help!
