Guys I had mine sitting in the “promotions” tab in my gmail with all the credit card ads and -Yoink- from any retailer from target to best buy that’s ever collected my email. If you haven’t checked that and/or your spam folder. ( promotions is a seperate folder from spam in Google) yal may wanna go check it. Hope this helps somebody. 
Good call, OP. That’s where mine ended up. Thanks
These emails aren’t actual invites but more confirmation that you’ve been selected.
Messages on waypoint & another email will be sent out tomorrow when it goes live with actual details on how to download etc.
Its possible some people won’t even see their email for whatever reason.
For anyone who hasn’t got a email yet,
Be patient, mine took 6 hours to come.
Check waypoint when the flight goes live for details on how to play (if you’ve been selected).
