Help with restoring plane purchases

Hi I got infinite flight on my phone a while ago and bought some airplanes. They finally put infinite flight on the Kindle fire eight Amazon App Store and I bought it. I signed in with Facebook and tried to go and restore my plane purchases but I can’t restore my planes and I looked on my phone where the restore button is but it not in the same place as the kindle. I do not know if the kindle has a restore button or not. Can someone help me figure this out. Thank you for your time.
