Is stadia still active? because i just ordered the premier bundle.
Sure, it's still active, so once you install your chromecast on your TV, you can enjoy Stadia there, but you can also already go and play via a mobile device and the Stadia app or in the Chrome Browser via stadia.google.com.
If you redeem also 1 month Stadia Pro for free, you can directly claim games and play them, so you don't need to purchase anything to go ahead and play.
I recommend this guide here for you to start with Stadia.
