Level 50 car needs to level up more to upgrade using a tune in Rivals car select screen - FM Report New Issues - Official Forza Community Forums

I was upgrading the Holden A9X Torana to A Class for the new A Class races and kept getting a message that my level 50 car didn’t have enough points to upgrade and that I needed to level it up more. This was on the car select screen for A Class Rivals. I was able to upgrade it by going into the My Cars menu and selecting it from there. This happened after the latest update but I don’t know if it was doing it beforehand.
