I am not able to update to the latest version of XD (28.x.x.x). Currently my version is still 220.127.116.11 and i have tried all the solutions in the forum such as uninstalling and re-installing and others and still no results. All my colleagues have updated successfully and now i cannot opent their files and as it is not backward compatiable. Can Adobe do something about it as it is really hindering the ability to collaborate. Appreciate if Adobe can ensure backward compatibility, especially when there are so many people facing update issues.
