Over the next few weeks, we'll be improving the security of our payment systems in compliance with EU's Revised Payment Services Directive. As part of this change, we're resetting all saved credit and debit card information. After the reset, you'll be able to re-save your information the next time you purchase RP, if desired. Additionally, depending on your payment provider, you might get two factor authentication prompts you're not used to, or you might not get prompts you were expecting to see.
This update will happen in waves, so some of you might experience the changes before others. For more information, head to the Player Support page linked above.
