I've played all but 3 five bn game. This game was going great until I tried to use a hint, that I purchased and now it's frozen the hints. I always purchase hints when I need to. This is the 2nd time I've purchased the biggest hint amount and 2nd time my hints were unusable. I had 114 hints left and I'm very angry 😡. Fix this by refund somehow, and I'll give this 5 stars as I've done all others.
