Same case for me , but I preordered standard , cancelled it and i got a refund, then purchased it after launch. Pearl Abyss gives the same reply to repurchase 3000 pearls for account unlock. Now I cannot even launch the game , a message comes up to re-purchase it from playstation store. I have notified Sony who is processing the case.
In no way they should not have locked anyone from the game. Get the technical issues sorted , end consumers do not have to deal with this process. What they say about they notified us early is not an argument.
Do not put anything in my account that I am not entitled to . Since I cancelled the pre-order there should not be any items in my account. Fix the game !!! Hopefully Sony will do something about this.
