Cant sync between all my devices

I bought the app on my iPad with deluxe version and I cannot get the deluxe version on my iPhone. I would like for the app to sync with all my devices. Additionally if the app is removed from your device due to phone change or whatever you will have to re-buy the premium albums because there is no recovery option for me. Also, I cant remove the ads and apparently you can remove according to the description. Overall it is a cute app with a lot of interesting wallpapers.
