Hi, maybe you have noticed that sometimes you cannot buy my apps on the webstore. It is because of SCA, and I am now urgently implementing new payment for european customers. Strong Customer Authentication (SCA), a rule in effect as of September 14, 2019, as part of PSD2 regulation in Europe, requires changes to how European customers authenticate online payments. Card payments require a different user experience, namely 3D Secure, in order to meet SCA requirements. Transactions that don’t follow the new authentication guidelines may be declined by customers’ banks. Soon it will be available for all customers on my website. You can still buy my apps, if it is possible. Ruslan.
