Paid for Pro but doesn’t register I paid for it – Sudoku: Classic Number Puzzle Review

I even deleted and re-downloaded and now lost my streaks too. I tried to restore my purchase and it just closes the game. I paid for a yearly subscription to use all features and evidently wasted my money because I don’t have all the features and it still says upgrade to pro. Please fix or I will seek refund from Apple. Thanks. Otherwise I like this game although I don’t like subscriptions. I prefer to pay for a game and just have it.
