Thanks.

UPDATE:
The problem seems permanent. Because the opponents are confused during the race (they can't see my cars) I tried to go back to my old livery or different one. It doesn't work. I have no car in the menus or during the race. This bug need to be sorted as soon as could be otherwise I could results to be excluded from the league I'm racing.

Hello Nigel,

This should be fixed now. Apologies for the wait.

Thank you José!
What about the token I used for the livery? Is it lost? :(

Sent!

Thanks! You are a true gentleman! by the way I stepped into the same river and reproduced the bug :D (changed the livery and car disappeared)
The good news is that somehow I managed to start the livery editor in the PC app (I have issues with PC app as it doesn't move on from version screen) and my car came up after that. Strange but luckily sorted for now. 

Hey Nigel,

The problem is known and isolated to some devices, we'll try to address that in the future. For the moment the workaround is what you found. I have also compensated you the tokens lost since evidently your intention was to have that livery and not a grey car.
