Your account is not authorisedto play haloinfinite

Hello, after I have received an email specifying I am allowed to play in the 2nd weekend for the halo flight, this annoying pop up keeps appearing. I have signed out everyone but myself, uninstalled and reinstalled but nothing allows me. Please help me out with this.

The “Not authorized” message that appears is because the flight is currently offline and not scheduled to start until sometime in the evening, west coast time [PST]. An exact time has not been released yet.

If you are still experiencing this issue after the flight goes live, check that you are on the correct account or your account isn’t logged in anywhere else.
