When I send clients links to artwork in XD, they always complain that they can't see the navigation controls at the bottom of the screen – and it's because the cookie acceptance banner (which usually gets ignored) is in the way.
I really think the cookie banner needs to be positioned somewhere else, where it isn't overlapping important features like the nav.
Thanks for reaching out. I am afraid, that option is not available as of now, however, it does sound like a great feature request so I will share your feedback with the Engineering Team and you can do that too by creating this request:https://adobexd.uservoice.com/forums/353007-adobe-xd-feature-requests
This is the best way of communicating with the Engineering and Product Management teams regarding issues and suggestions so they can be implemented in future releases.
