Buying Uplay keys on the Humble store is apparently still1 fucking broken.
Spent half an hour debugging it with a friend, and apparently you just... need to use edge as a browser? Like, all the other browsers just get stuck in an endless "you need to go to the ubi site to connect to ubiconnect/you are connected to ubiconnect do you want to continue to the humble site" loop. But with edge it "just works".
(no, of course you don't get an actual key any longer, Because Capitalism and resellers)
I wonder how many Cookie Crimes™️that dogshit setup uses, that all other browsers are "hahaha no" about now...
1: Apparently for the last 4 years, judging by some of these search results?
