Grand Theft Auto Online is a bit of a mess right now but it’s nothing that a few patches can’t fix. For some even going through the tutorial is a massive pain because the game keeps getting stuck at loading.
Rockstar has now posted some short fixes for the said problem, which hopefully will allow you to play the game until an official patch is released. The following fixes are for those who keep on getting stuck on the “loading session” or “waiting for players” screens.
Delete the title update from the Xbox Home menu or the PlayStation 3 Cross-Media Bar, and relaunch the game. This will force the update to redownload. This tip worked for me when I was experiencing the problem.
- On PS3: Navigate to “Game Data Utility” from the game menu. Select “Grand Theft Auto V” (not ”Grand Theft Auto V Install”). Press Triangle and select “Delete.”
- On Xbox 360: Select “Settings” from the Home menu. Select “Storage” and then “Hard Drive.” Press Y and select “Delete System Cache.” This will delete the game update, but bear in mind it will also delete updates for other games.
Select “Swap Character” from the Online tab within the single-player pause menu, deleting the character that was unable to get into the tutorial, and then create a new character.
This is not the most ingenious idea, but Rockstar says: “Some who were experience this issue have been able to get in just by trying again later.”
VentureBeat has posted one of their own fixes that asks players to start playing GTA Online in Solo mode. From the single-player menu, select “Online,” and then choose “Play GTA Online Now.” Select “Solo session” from the menu.
