Steps to reproduce

When I navigate to I see a welcome page that has a “Sign in” button (“Iniciar sesión” in Spanish). When I click on it I go back to that same welcome page instead of seeing my inbox. Cannot repro on other browsers.

I can access other sites that also use Microsoft Account, like OneDrive, without issues. The only extension that I had installed was uBlock, but disabling it didn’t help.

I have attached a video of this.
