hello, I look on internet sites and when he talks about stadia he says that there are 2 offers:
the pro one
and the free stadia base one and yet when I register I am offered that the paid one
Why
thank you in advance
Welcome @HyperCops,
You can skip the Pro subscription the easiest by starting one of the free games on Stadia.
Go to the Destiny 2 page or the Bomberman page.
Now you should be able to start the game with your Google account without starting the Pro trial subscription.
If you initially set up your account when "purchasing" a free game you won't need to sign up with a credit card.
I don't know if this is the official solution but I just test drove it with a throwaway and it works.
