Rank and Service Record disappeared/unavailable

Okay so I’ve been playing Halo 5 Arena for a few days, but all of a sudden today my rank disappeared back to a 1, and my service record is unavailable. No game I play is registering after either. Any help on how to fix this?

Chances are that it is just a bit of lag connecting to their server, just back out and sit on the homepage for a few minutes and let it sort itself out. If that doesn’t work then sorry mate, I’ve no idea.

Could it be from the update ?

How do you guys find this stuff? This is from a month and a half ago.
