First, I want to say I love this game and enjoy it very much! It keeps me thinking, which is great. Not too easy, not too hard. However, I paid for no ads a few months back and suddenly am receiving ads again. I did not get a new device or delete and redownload the app, and when I click restore purchases I get an error. I would love if this was fixed because getting an ad every few puzzles makes me not want to play anymore!! -hence why I paid for no ads!
