I can't confirm the placement of the cats on the boat when clicking confirm. How to do ?

There's a few things I can think of that may cause the issue, let me know if none are the cause.

When you're placing there are 2 confirm buttons. There's a little confirm directly above the piece which you have to click first. Then you can click confirm at the top of the screen to end your turn.

If you can't click the little confirm above the piece after you place it then it's because you can't place it there. Either the piece is off the boat, overlapping another piece, or not touching a piece you already have placed.
