Since a recent update every font has been 'missing' in XD. They're installed locally and I have them through Adobe Fonts. I've tried going back to a previous version of XD to no avail, I've also tried disabling Adobe font sync and re-enabling.
We're so sorry for the delay in response. Could you please confirm if you are facing an issue with the latest version of XD which is 35.1? If yes, please try re-installing fonts and if required Adobe XD and let us know if this helps or if you need any further assistance.
