I experience the exact same issue as is stated above by multiple users. All xbox services report no issues and the 2 url's provided by @BarryBL show 2 green checkmarks. But still the game does not load into the main menu and is stuck on 'communicating with online services'.
I have no issues with playing other (xbox) games online, not even F1 2018 and earlier
all combinations of reinstalling, logging out/in, restarting do not work
Windows is reporting that xbox live services are up and running/connected and NAT type is open
Can someone from codemasters please take this issue seriously?? we are paying for a litterally unplayable product...
Looking forward to a reply soon..
