Account address issue has STILL not been acknowledged by Square.

That's the problem. Because the payment processor refuses to accept US dollar payments unless the card has a US billing address. That's what I've been saying. Even awful Paypal does this. God help you if you have USD bank accounts outside the US, the payment processor will be "nope, you are in the EU, you pay in Euros" or "nope, you are in Canada, you pay in Canadian Dollars". That's the purpose of this "feature". It's likely that they even use different banks in different regions to minimize the currency exchanges.

I'm actually not sure that that is the only problem, in EU at least. I've seen some say that they have had issues with the new payment processor even when they've tried to use Euro currency bank card from country Y after registering euro currency-using country X.
Additionally there a quite a few countries in the EU that do not use Euros (Denmark, Norway, Sweden, Hungary, Poland) etc. that are not charged in their local currency, but in Euros by Square.
So I would not be surprised if the currency issue that you have in NA is not applicable to EU, or at least not applied unilaterally.

All Square Enix has to do to fix this is allow users to use any payment card they have, and select the currency to charge it in. That solves everything. Ignore address verification as long as the name, card number and expiry is correct. When people go into a physical store, they are not asked to verify their address with the cashier/self-checkout. If it's the same payment card they've been using for the last 14 years, why the sudden incompetence? Did "Square Enix" get a better deal from another payment processor, who happens to be sorely incompetent (see the VISA Debit issue), or is it simply they are trying to "protect" accounts from using stolen credit cards/gift cards/prepaid cards from foreign countries?

Yes, if they want to use address verification as a 'security' feature then they have to not implement it so half-heartedly. I'm still shocked that no one that was even a little bit familiar with their account management system couldn't see that this was going to be a huge problem. Was nobody consulted?!

There is no reason to tell players they need to make a new account.

100% agree. Absolutely shocking customer service and such a disservice to the people that have supported the company for so many years.
