Halo Waypoint Tech Preview Access

Was anyone else confused by the way the access codes got sent out for this preview? I did not get the message on the Halo insider website and was only able to access it by downloading accidentally going to the Halo Waypoint Website. I never got the message on Halo insider like I did on the previous flights. I feel like this was a little confusing and It could have been made clear from the beginning that the next fright info would be done through the Halo Waypoint website. What do you guys think?
