You can pin a canvas to a workspace so that the canvas cannot be moved or resized. When you pin a canvas, you can still move its contents – adding and removing assets as needed.
To pin a canvas:
- Tap the canvas title in the top-left, just above the border of the canvas. The entire canvas is highlighted, and a toolbar opens.
- Click
(More). A flyout menu appears. - Click on Pin.
The canvas is now pinned and in a stationary position. To confirm that your canvas is pinned, look for the 
(Pin) icon in the top left corner of your canvas.
To unpin a canvas, follow the above steps and click Unpin.
The same actions can be performed on both the web and wall client.
