Driving in Milan/clean air charge

[Oly 190360]

Hi all , looking for some help regarding driving in Milan. We going to the Monza GP in August and we are looking for some information regarding clean air charge . I’ve contacted the tour agent for the campsite we are staying at and they said they have not heard anything about it . But when l’ve put the directions into Apple Maps it says that there is a charge. Has anyone driven there recently and know if there is a charge or not .
