I am trying to pre-order endwalker via https://store.eu.square-enix-games.com/
When I try to verify my payment info, this message appears:
"Please wait while your payment information is verified by our banking services. This may take up to 1 minute."
Followed up with: "An internal error has occured. Please try again in a few minutes."
This happens on my laptop and on my mobile phone. Both using Chrome as browser.
What can I do to fix this?
