So I’ve made some progress, with 20,000 XP, from playing Campaign missions, and I’m now a Private Second Class, but… I see that I still haven’t gotten any seasons points. I do not have Xbox Live Gold, so… Am I missing something or is this still being tested?
Hey OP, you can get this fixed if you file a bug report about this on the Halo Support site: https://aka.ms/HaloSupport
Huh… thanks for the info. I’ll get on that. How do I submit a request, or inform them about the bug, for potential fixes?
Follow the link I posted and then look at the “How to submit a ticket” article
Ah… 
I kind of figured it out. I went offline, restarted my game because it glitched on a playlist I was doing for an achievement, went back online at the start screen, saw the notification that I got some new items in the Option and Career menu, find that I’ve got three seasons points, and already bought me the first 3 helms on the Season 1 pass. I’m glad that I can do Campaign challenges for seasons points, and it’s even better when I don’t have to use Xbox Live Gold, because I don’t use nor do I have Xbox Live Gold. I’m on cloud nine, but I could use some chocolate and peanut butter right about now.
