Not able to take tiles maybe user error – Real Mah Jongg Review

I am new to Mah Jong. So this might be the issue. The three star rating because I cannot find a help section in the game. I start collecting the tiles I need, and then I can never actually lay them out. Meaning if I have four of the same etc I can’t put them out on the rack. It just starts the process of take a tile, skip, once in a while take a tile but I can never actually swap a tile on another players rack that I need, for example I can’t put an appropriate tile in order to take someone’s Joker.
