We're aware of an ongoing issue where a forced update on Xbox One subsequently prevents players from connecting to the game. The problem is under investigation, and we apologise to those impacted for the resulting inconvenience.
Update [00:40 CET]: The issue should now have been resolved, and an updated version of the game build is progressively being rolled out to all Xbox One players; this new build replaces the previous, incorrect version that was erroneously pushed on Friday due to a data transfer error. Once this new patch has been installed, players will be able to access the game as usual.
Should you encounter an error code while trying to update, please try a fresh install of the game.
Thank you all again for your patience and understanding.
