No version of Monza is playable in the online X Class lobbies, as well as other variants of tracks that were playable in FM5.
Monza is not in FM5, do you mean Le Mans? Something is wrong with Le Mans in multiplayer, few people always start before everyone else
I know Monza wasn’t in FM5. I’m saying it’s not available in in FM6 X class rotation and it’s an actual GP track. Variants from FM5 aren’t in there either but they include top gear test track and lime rock which are terrible for X Class. Not to mention the night races
