Additional comments:

My engine supply has been opened, but even though I use the points for the tracks, my 101 points still remain as 101 points.

Same happened to me - clicked on save but it didn't and when you exit it discards the upgrade whether you save it or not.
Update: Wouldn't let me do it on PC, but seems to have worked on the app.

same here , on pc , i tried mozilla & edge as browsers but no good .

Hello managers,

As mentioned, you may have old code being cached, please read my comment above and follow the instructions.

Clearing cache half worked. I have +6 on the next track to race on through engine running. +2 through fuel supplier.  I only get the +6 and not the fuel supplier

On iOS 16.2
