Not working :C

Two things:

Last month I ranked in Arena, yet I didn’t get the Season Emblem for that, what’s up with that?

And two is Halo 5 won’t connect to lobby services on my home internet for some reason (cant even do custom games by myself), I have to connect my Xbox to my hotspot to be able to play, any news on that??

Sounds like your ISP is down. Check to see if have internet on your PC.(email, web, etc)

to issue one, the season was extended. in game it now says June-July season when you hover over ranked playlists.
