Hello! Welcome back. "Cannot Move" means you can make copies of the tile. I use this when I want students to use a tile as a template to make infinite copies of a tile. Or when I want them to roll a dice, but not move it. You can interact with a tile, but not move it, delete it, etc. "Locked" means you can't move it, can't make copies of it, can't roll it, can't change color, etc. Hope this helps!

Hi Rachel. Our app does not have the same functionality as using the site in a browser. To access your saved Polypad on an iPad, open Polypad in a browser winder. We do hope to update the app at some point, but for now must of our energy is focused on Polypad improvements. Thanks!
