I recently purchased the Stadia Premiere Edition and received an invitation code. How do I redeem it on my existing account?
Also I didn't see any discount price in the store according to https://www.androidauthority.com/google-stadia-game-prices-pro-discount-1056213/. Are they all expired?
the invitation code or the 3 month free trail work only on brand new Stadia accounts.
Stadia deals have only a limited time to be purchased / claimed. In this case, the period of the article seems to be over.
