I’ve been an insider for about a year now - or however long MCC has been on steam - and I’ve been getting Insider keys just fine so far. Even so I went through and made sure I had everything checked out as per the 343 tutorial video they posted. I’ve double checked and triple checked my Insider page and email for a key but I haven’t gotten a Halo Infinite Insider Key yet.
I get that today isn’t the day for the beta, but I really do hope I get a key. I’ve been so excited to play and try out this game ever since it was announced. I hope this is just a server issue on their part and I may get a key by tomorrow. Still holding out for hope.
