Latest update:
Hello Xbox members, we’re currently experiencing an issue. We apologize for the inconvenience. Please check back for updates.
Sorta kills Forzathon plans for the evening 
Hope they sort this soon.
On PC, I have not been able to access the games FH3, FM6: APEX, and the Forza app since 7 hours ago.
Was disconnected from a co op race
Havent tried again
Already got the challenge done
Yeah got mocked off on my last race to win the Porche for the Forzathon and had a great time going as well
Update, its now worse. lol
It lets me log in, A/H works, Forzathon is there, all tabs are active…
But in the garage not so good
my designs = zero
my tunes = zero
and if i enter my cars the game just stops and locks up looking at my current car…requires a quit game
YES, I rebooted and unplugged the cord and boiled it for 5 minutes in distilled water.
I’m just leaving it until later.
Sounds like you need a hard reset hold all those good steps, also try persistan storage in Blue ray or resetting you’re modem
Yep had my first game crash while in Co Op game first time arround and it took about 10 minuits to synchronize for the next Co Op game but was fine after it synchronized Also noticed garage took a whilr to populate had a heap of blank spots for a few minuits.
I was logged out of a Paladins game so looks like xbox live playing up.
