Hello,
I have the same probleme as you.
But when i click on the red box where i had my shadowbringer early Access key, i have the following awnser :

Sorry, your order has not been validated.
If you have problems with your order, please contact us at storesupport-eu@square-enix.com

But i am lvl 80 and played shadowbringer...until yesterday.
When i go to the square enix store and go to my purchase history, there is nothing.
Anyone know what i can do?
I dont know whats going on with my account
