I bought NPC Codex on Dec 1st, and tried to get the discount on my FGU account to use it in game.
It's always worked before, but I was unable to update with the purchase.
Checked the FGU forums, tried suggestion to deauthorize, then reauthorise.
Now states that the authorization token is invalid so I cannot sync them at all!
(I have logged in and out of FG, logged in and out of Paizo, deauthorized and reauthorised link with Smiteworks on the Paizo site)
I understand there may be issues, but it has been two weeks and I am still unable to use it :-(
