I am having issues with Adobe XD Share links not providing full-screen views of my web designs. When I activate a link, I now see a white gutter on the left and right, as it is not scaling to view full-screen. It does not matter which "view setting" I use. Also, I have an older link that I did not update from a previous project that worked in full-screen, and once I updated the link it now has the same issue.
We are sorry to hear you are facing issues while previewing the XD prototype link. We would like to know if you are using an external monitor? If yes please unplug the external monitor and then try to preview the link. If no, please share the link with us here so that we can check at our end. What is the OS and XD version of your machine?
