hide the OS menu bar
When the prototype is added to the homescreen on iOS, you should be able to set it so it opens over the top of the OS menu bar.
This is useful because the artboards are created at the size of the device screen, but when you load the prototype, all that does is make the screen slightly too large so it does an annoying little scroll, or knocks the elements off the bottom when they should fit perfectly.
Other web-based services allow this so you'd expect it to be a basic feature when designs are encouraged at the full viewport height.
Not sure how to reply as I received this reply from Elaine at Adobe:
"Unfortunately, mobile Safari doesn’t allow you to go full screen. In order to get this to work, you can save a link as a bookmark to your Home screen, then launch from your Home screen. You’ll get it in full screen at that point. Please note that you can also demonstrate using the Adobe XD mobile app, which defaults to full screen.
Hope that helps!
This is true for other services like inVision, which is why i'd already tried this, but it doesn't seem to work that way from an XD prototype - the menu bar remains. Is there a setting you need to click in the app to get it to do that? Or is this a new bug and it's isolated with me?
