Hi @dg177478 and welcome to our Community!
The best way to get full screen is to download the game to your PC from Microsoft Store here and then click on the full screen mode up to the right in the app.
You can sync the levels from Facebook to the Windows app by connecting the game to Facebook when you open it.
