Why is nothing loading?

[EthyHunt2942 0]

I pre ordered the game a few hours before release (midnight last night) in order to have it downloaded or at least at the ready to start point at release, when it got to release I started the game and on attempting to enter any kind of session that was supposedly downloaded it would stay in the loading screen after selecting track and car and options with a small ‘please wait’ box at the top?? Do I need to reinstall or will there be an update soon that would kick this into working? I’m playing on Xbox One
