I thought I was missing some of my content too, but apparently there are two places from which you can access your digital content:
One is via the store page -> your account -> library
link:
https://store.paizo.com/library/
This does not contain anything purchased before 2020.
The other is via the Paizo main page -> my account -> digital content
link:
https://paizo.com/paizo/account/assets
There I found all my purchases.
