Yeah...I tried my damnedest to claim some Call of Duty game that "came with" my 3080 last year. By the time I was done, I had to sign into "GeForce Experience" (which I'd avoided up until then) and install battle.net, reset my old account from the last time I had it (I think when Diablo 3 was new), then I had a hell of time because the authenticator was tied to an old device but I couldn't manage it without logging in.
I forget what eventually happened, but I never was able to play that stupid game and I only even bothered because it was "free".
