I've looked around for answers to this but nothing's really come up. I understand that Stripe is implementing Strong Customer Authentication (SCA) in September 2019. I have a couple of legacy sites, that use much older versions of Expression Engine and Expresso Store. Can anyone provide some guidance on how I can continue to take payments on the site after September 2019? Upgrading the add-on isn't going to work in this case as everything was built such a long time ago, and it would mean a total rebuild.
