That's because you go back to the place the story ended from 2.0, ie not Mor Dhona.

2.1 story started at waking sands iirc.
I'm pretty sure it starts in the walking sands (vesper bay).
Waking Sands -> Minfilia. There should be other quests in the room with Thancred/Y'shtola/etc too.
Try do see where you stoped in your quest log (tab quests completed, filter story quest). Then go see the patch notes of 2.1 and/or 2.2 and figure out when you stopped and where to take next quest (the npc that give you the quest is indicated in the patch note).
Gl ;) .
You have to be up todate on the story, and had to of beat king mog normal, and ifrit extreme. Then talk to the guy in the waking sands.
