Does not recognize my touch – Tavern Guardians Review

I tried over and over to match tiles but the game does not recognize my finger movements when matching three. Besides being a Match 3, I don't understand any of the basics. Help please, what am I doing wrong. I'm on an iPad Air2/128G with recent iOS updates. I have no problem typing this review so it is not my iPad. Your game JUST does not recognize my touch at all.
