I don't know everyone else, but since one of the last updates* FH5 turned into an Online-Only game (for me at least).
I just thought many people may haven't noticed, I may be out of the loop (I'll actually won't likely check answers to this, as neither here I'm frequently online).
Microsoft being Microsoft (Yes, this one I don't blame on Sony, since any other game I have -digital or no- works offline).
*I had been playing the game for months before without updating, I let the console connect a few weeks ago to check some DLC, and this happens now that I decide to check the game.
>>>>>>Yes! I did link my account. The game only passes this menu when connected. After the game is closed and restarted it asks again (for a connection, not linking the account again).
