I have tried signing in to the xbox app on pc, Which I used to be able to do. But for the past six months I haven't been able to and I've tried everything, from services to reinstalling the app.
In short, I click "Sign in" on the xbox app, it takes me to a pop up, and the sign in button there does nothing. I click it, and nothing happens. I do not get an error message, nothing- Its as if the sign in button simply isn't connected to anything.
