Sony's newly-released Gran Turismo 7 has been essentially unplayable for almost 24 hours as ongoing server maintenance continues to prevent GT7 owners from accessing the game.The problem has been reportedly pinned to an issue relating to the most recent patch, but there has been no further update from the Gran Turismo team in the past 16 hours and the game remains offline.Due to an issue found in Update 1.07, we will be extending the Server Maintenance period.
