I was registered for Insider before September 13th, but I did not realize I had to opt into flight invitations too. I just registered for the flight invitation earlier, but I was wondering that since all the announcement said I had to register for was Insider before the 13th if I would still get a flight invitation? If not it’s not really a big deal, but a lot of my friends are playing and I’d love to play halo with them like the old days.
