To load those tabs, you should be connected to the internet. We understand that you can’t start the game without internet connection, but sometimes if you’re connected to the low quality internet connection the game itself will load, but social, friends and community tabs will not, because these aspects of the game require better and more stable internet connection. Our suggestion is to wait a bit for these tabs to load, or to try and connect to a higher-quality internet connection and then attempt to reload the game.
