Volkskrant.nl after login, the site doesn't recognise I'm logged in

Website: Volkskrant.nl (Dutch newspaper)

Problem: I have a paid account on said website to read articles but while using Brave I can log in to the site but immediately after logging in it’s as if the site has forgotten I have logged in. It asks me again to log in. There are no error messages given.
Only with all the Shields Down does the site work properly.
Toggling each individual setting (ad control, cookie control, etc.) doesn’t fix the problem.
Also, trying to “read the newspaper digitally” by clicking on “Krant” in the top right corner doesn’t work unless all Shields are down. (see screenshots)

The message reads: In case you use browser plugins that block functions you need to add an exception for the domain gigya.com.
This is our identity provider which is necessary for a working login.
