The Infinite Canvas is very large, and it is possible to zoom or pan far away from your work. Here is how to quickly find your drawing again on each platform.
Concepts for iOS
When you navigate away from all of your strokes, small gray arrows will appear at the edges of the screen. Tap any of these arrows to instantly navigate back to the nearest part of your drawing.
Pro Tip: If you are zoomed in or out too far, Tap+Hold the zoom percentage in the status bar. You can then enter 100% to return to the default zoom level.
Concepts for Windows & Android
In the top right corner of the canvas, double-tap the zoom percentage field. This will instantly reset your view to 100% zoom and center the canvas on your drawing.
