Game Freezes & couldn’t restore purchases – Galaxy on Fire 2™ HD Review

I can’t finish the supernova expansion, which I’ve had to buy twice because I couldn’t restore my purchase. Every time I use cloak or the enemy uses cloak the screen freezes, but the game continues. I can get out of the screen freeze while boosting, but once the boost is over it freezes again.... please fix this!
