I hear I have to be online to get past the start screen but after this can be played offline. If this is true, what modes are playable offline?

Title.

When I'm defending the try line I'm able to stop their forwards but since none of my other team mates help they always fall over the line? is there a way to make it so that my team helps with the tackles more?

Says it needs to be online to play, but it doesn't connect. The servers must have been turned off?

Is anyone else having trouble getting into the Fanhub ?
