Can't scroll right beyond certain point in Sketch document

I have a large Sketch file with Artboards that go very far to the right of the screen, however Adobe XD only allows me to scroll right to a point, stopping me in the middle of an Artboard. I am able to see these unreachable Artboards in the layers list on the left toolbar within XD, but clicking on the does not bring me to them. Seems like there is a fixed "max width" of a document in XD and this Sketch file has surpassed that width. I don't have a Mac anymore so I cannot open this file in Sketch and simply move the Artboards below existing ones to reduce width of the document.
