Warning: Had to purchase TWICE - NOT HAPPY! – SET Pro HD Review

Purchased and downloaded on my iPad Air. Wanted to use on another device since it is smaller (Mini) and wasn't listed on my purchased apps. So deleted on Air hoping it would be available in my purchased apps. No such luck....had to purchase again to get onto my Mini. And now it's not on my Air anymore. Not happy. LOVE the game, play with my students, but feel ripped off by the company. Purchased twice but still only have it on one device. Why can't I use on multiple devices? Why didn't it stay in my purchased apps?
