Hi Bluescape support team… reopening this “ticket” with a little more information as the previous one closed after 30 days.
We’ve noticed that when and owner or a facilitator hides a canvas, editors are still able to blindly click around until they find text objects, etc. and are able to edit them or even move them outside of their hidden parent canvas. Please see attachment mp4 for a little clarification.
In the attachment, you can see that I created a canvas, hid the canvas objects from view, while another user (an editor role) was able to select the textbox object, and move it out of the canvas to read it.
Preferably, once a canvas is “hidden”, it cannot be manipulated to allow others to see the content. Please let me know if you would like any more information.
