Just to update where I can on the major issues at the moment:
2020 Revised Calendar Schedule -
As developer and publisher of F1® 2020, the official videogame of FIA Formula One World Championship™, Codemasters has accurately recreated the original 2020 season, which was scheduled to start on 15 March. Due to time needed to re-create the circuits in-game, it is not possible to include any of the new circuits added to the revised 2020 season.
F1 2020 Online Services Maintenance - Online services are back. They were down to address an issue in the esports event which locked fuel assist to on after the first attempt.
