Same here, few days ago some gamers reflect Forza hub do update on several games. Seems it's not the same for every one.
For me, only gamerscore updated before and now
FM7, FH4: Only gamerscore updated
FH3, FM5: Update everything
Cannot check for FM6 as it's already 3000 pt.
I keep playing different Forza games just to check how Forza hub reflect
You'll never play alone!
