100% Preview in Prototype Mode
Very annoying that the Preview window is not at 100%.

Zoom in the Preview Window
Also note that the "Viewport height" setting will determine the scale of your preview. Make sure to set that to a value slightly smaller than the height of your screen - otherwise XD will shrink your design and you'll have black bars on the sides. (I don't like or understand this, but that seems to be how it works.)
Suggestion to Adobe: ignore the viewport height, and just render the design based on the artboard width. Or make this a setting/option. In either case, this needs to be more obvious because lots of people on lots of forums are, like myself, confused by the size at which the preview is getting rendered.
Is this fixed yet?
I need to view my text at the size it was designed.
I designed my artboard at 1680 wide to match the width of my 2019 15" MacBook Pro. When I preview my file I still get bars. I check the browser width and its 1680, I check the zoom and its 100%.

Please elaborate. The preview window is in fact at 100% unless the entirety of the design doesn't fit on screen. For web-sized artboards I would recommend introducing a scroll viewport to your artboard that what the content will be at full fidelity and you can scroll to view the entire page - thus fitting on screen and not being scaled.
