I’ve checked several times and I know that I have completed more car masteries than it is showing on the Rewards page. I’ve had an issue where progress doesn’t track until I play the game again, but I’ve played Horizon 4 a lot and it’s still not changing.
These updated every sunday in the past.
i had this same problem…
days i would check it and my car masteries would not update i had 328 i think…or more…i had done 64 plus cars and still nothing…
then in the last past few days may be sunday it updated…i have all hub done…3000 rank
It took nearly 6 months for mine to update correctly
