This appears to be an old issue - I have seen posts from a year back on this. As the subject says, the SF Pro Display font does not display correctly on the XD iOS app. It gets stretched. It is a major problem for designers, since they have to put paddings and margins differently in the actual artboard so as to see the intended look on the preview on the app, but then the developers code HTML and CSS to match what is on the artboard.
I have seen posts by Adobe employees on previous threads that this is being looked into. I would like to request them to expedite it if possible, and also post an expected date by when this will be fixed. Each day using XD is a problem for us since we use SF Pro Display for all our screens.
I would also greatly appreciate suggestions from anyone on any roundabout way to bypass this issue. Thank you!
I also chatted with Adobe XD live support on this website, but they weren't able to help either (they got me to uninstall and reinstall XD on all my devices and reboot the devices, but that did not solve the problem).
