Glitch at the bridge. Every time my child gets to the bridge and you are asked to place the pieces back they never move. The train is always stuck in the tunnel. I thought it was because of the age of their tablets ( Samsung 2018 Tab A). I trade up and now they have the 2020 S6 Lite, Samsung. Your game still has an issue in the exact same spot. Other than that your game is delightful for my autistic child. Help!
