I purchased Affinity Designer in Jan 2017 via Mac App Store. It is at version 1.6.1 on my Mac. I am unable to find how to update it to the latest version. For example, if i open App Store and find Affinity Designer in App Store, it simply says OPEN, there does not appear to be the option to update it. If i click on the UPDATES menu item in App Store, it says all my apps are up-to-date. I have contacted Apple Support and they said if App Store is not giving me the option to update the app, then i should contact Affinity Designer App Support. Which is what i'm trying to do here! Thanks!!
