I think I know what the problem is- I've purchased the Steam key from a third party seller. In the launcher, I am logged into my Paradox profile as well. I've also bought two DLC recently, the Heirs of Alexander DLC and the Epirus content pack, but they function fine, although, once again- no achievements. What's strange is that my copies of Crusader King II & III work fine with achievements, but they don't show up on my Paradox account either, for the reason above, most likely.
Any advice on how to resolve this would be greatly appreciated
