Best Lap Times not updating in Leaderboards.

Can anyone tell me why would the best lap times not count with a different car from the same class?

I have beaten my supposed best time within 4 different cars of the same class in the same track, both racing and challenging rivals and the leaderboard does not update… What gives?

Are you beating the lap with clean laps?

sometimes the updating of the leaderbords are down.

I had that problem a moment earlier with my drag times but i got a new record and it updated so meh, it’s all good.
