signing in to the app on PC from console

Thanks for the update, may I know if you tried putting that PIN wrong three times (or more)?

Sometimes when you put the PIN wrongly, a "can't remember PIN" appears and you should be able to sign in with your password

yes I am referring to the pass key and i can sign in on another account but I don't want to pay for everything again

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today Canibb

When you say "Keystring" are you referring to the pass key created in your Xbox Console?

And, if you try creating a PIN for the actual user in your PC and use that instead, are you able to login properly or an error appears?

I'll be waiting for your answers, greetings from another Microsoft user

Hi. My name is Brilliant and I am happy to assist you today.

You can download the Xbox App from a Mobile Device.
Sign in the Xbox App with the same account.
Link the Xbox Mobile App with the console/PC.
You can access Games/Updates from the Xbox Mobile App, you may find games that are not displaying on the PC/Console.
Download remotely from Mobile Device to Console/PC.

I hope this helps resolve your query.

Is the issue on your console or PC? Try removing your account from your console then signing back in. On PC you can right click the Xbox beta app and select more, then app settings. Then you can reset and repair the app. When you sign into your MS account
on a browser, does your services and subscriptions tab show GPU is active?
