This is an expected behavior to invite users to create an account and/or sign in to edit and collaborate on the shared file, but I understand your frustration with not being able to view the design area to its fullest.

Thanks you for the response. Yeah we do have to zoom out and hide the Figma UI, but when we share designs with text that needs to be read, its difficult to see it in context having the bar appear above it.

Thanks for the additional context! Again, this is an expected behavior to welcome new users as well as allow them to comment, edit, and collaborate to your shared files as needed. And as you mentioned, you are still able to Zoom In and Out to see the full design.
That said, I’ve moved your topic from Get Help to Share Feedback for the team’s consideration.
