Just applied my "Experimental Upgrade Token" to my new Klingon Faction characters' "Suliban Silik Flight Deck Assault Carrier [T6]"
It unlocked fine for that Character, so then I went on to my Main, a Federation Engineer, claimed the ship from the Yard, & it is NOT upgraded to T6-X & wants a token. It clearly states this Upgrade is Account Wide, so please fix it.

Indeed you are correct, I moused over the button & it said I must be at the shipyard, so I went there & the Button Lit up.

Thank you for the education.
Shame the instructions were not in the paragraph above the grayed out button in the first place.
