Paid $12 to remove all ads cuz I was enjoying the game. Then all of a sudden game started to freeze up and become unplayable. Cleared the cache and restarted my phone to see if it fixed it. Nothing. Cleared all data including cache as a last resort after 4 months of this and lost all my progress. Not happy and wouldn't let me link the game to account to save my progress. Definitely upset in out $12. Won't ever download from this company again unless the fix the issue or give me my money back.
