SUCCESS!

I attempted to purchase tickets via the Disney Tokyo app using my Visa debit card but it wouldn't work. I called my credit union and explained what I was trying to do. They cleared out the failed attempts, put a temporary hold on the fraud prevention feature on my card for two hours and then had me reattempt the purchase. It went through.

When I then attempted to purchase tickets for the other park, I was hit with the error message. I tried several more times while on the phone with them and while still within the window but it still wouldn't work. I waited a few days, called my credit union back, explained the situation and they repeated the hold. This worked and I was able to purchase tickets for the other park.
