Forza Rewards Gamer Score not registering

just wondering if anyone else is having this issue?
I’ve filled nearly everything for the Forza 6 Rewards but the only thing that’s still at 0 is my gamerscore and it’s been that way since release, funny thing is I have 34 Achievements for the game already. everything else seems to update like miles driven, badges unlocked etc just gamerscore won’t.

It only updates once a week or so.

As above
It takes a couple of days for it to register with gamerscore
Funny the other stuff registers almost immediately though

that’s such a pain in the neck, if it updated it’d put me to Tier 9 haha. sucks everythingelse updates in a few hours.
