i got this message a few hours ago, “We’re excited to invite you to a multiplayer flight for Halo Infinite this weekend! To see all the details for this flight, including how to download your flight build, please make sure to check your private messages on Halo Waypoint.”
But there is no message in my waypoint inbox.
As I head to the waypoint it takes a while for the web page to load and says,
"PROBLEM DETECTED
Well, this is embarrassing. Looks like we have some problems on our end."
I cannot wait anymore to test out the build. Please help 
The same thing is happening to me, and I’m not sure what to do.

Same thing is happening to me, cant access my old messages/notifications now.
I’ve got the same email saying I’ve been invited to the flight, and it’s directing me to check my messages here on Waypoint. I don’t have any messages, but I do have a notification on here saying that I’ve been invited to the flight. But when I click on it, it takes me to the Insider support page and says “If you don’t see any other articles with flight information in the Halo Insider part of this site, it’s because you have not been invited to any currently active flights.” So confused.
Go to your insider profile the code is at the bottom of the screen under current flights, it is not in your messages. Hope this helps.
Yeah, this is annoying. Couldn’t they have just sent the codes out in emails?
I have the same issue, I have no new messages and the email link sends me to an empty inbox, no sign of the code anywhere
