Hi, I'm going to show you how to remove a tile from the app. First we go to edit mode by clicking the profile picture at the top right.

Then we click start editing, and then we can click the three dots at the top right in a tile. Let's say we want to remove the train. We click the three dots.

If we then scroll all the way down, we see there: remove train. We click remove, and then we confirm the removal here. Then we click, and we see that the tile has been removed.
