I'm only making this topic as I'm seeing that it's listed date is today on the launch browser (I guess they updated information/workability? Idk). The highlight is this tidbit taken from the FAQ page: https://companion-app.finalfantasyxi...ice-plans.html

Q. What does the premium service plan offer?
A. The premium plan offers a range of additional features.
Please note that the benefits will only become apparent once your in-game character is able to hire retainers, so please unlock that feature in FFXIV before considering upgrading to the premium plan.

PREMIUM

Use an extra chocobo saddlebag in-game, for a total of 140 saddlebag slots.
Manage chocobo saddlebag items.
Hire an extra retainer in-game for no additional cost.
Manage retainer items.
Exchange items between retainers.
Receive twice the kupo nuts per day and carry a maximum of ten at a time.
Premium plan features may be used by all characters on the same service account.


My reaction: And so...it begins...
