How the heck does online co-op work?

[dustin1280]

So my wife and I are playing this game, but having trouble figuring out coop....
First, there is an hour long timer? anyway to remove that?

Second, we can't freely swap between islands individually? We each have to be on the same island at all times?

Third, were weren't even able to figure out how to use "any" mode to move around islands....

Anyone have a co-op guide so my wife and I can understand exactly how it works?

Co-op is just as follows.
Go to the counter create a room. Or join one. Add a password to it.
Set it to either explore. Picking gnomorsia. (The large harvesting island)
Or a treasure grove. (Rogue like dungeon)
Do it for X amount of time.

End the session.
You and your wife will spawn on the host island. Until you set a new session again.

It's not a seemless co-op like everything else.
You can't advance the story while in multiplayer too.
Nor even interact with your skill points for your life.
