So I'm trying to copy and paste some vector artwork, logos, into Studio and am running into issues. Upon pasting, Studio seems to develop a mind of it's own in terms of how it interprets the vector data and things come out looking super wonky.
The top image is what happens when copy/pasting from Illustrator where the bottom is from Sketch - top is pretty obviously wrong, bottom is closer to normal but has some weird things happening in and around the middle of the F, O, and N. It's not just this logo, either, it's happening with a few other logos (but not all) that I'm working with.
I looked at your Studio "getting started" article on the subject of importing content and saw toward that bottom that it recommends saving vector artwork from other apps as an SVG and importing that file. The problem with this "solution" is that I can't import SVGs into Studio via the "Image" tool... they are greyed out in the import dialog box.
I tried importing using the File>Import option and get similar results as the Illustrator image posted above.
