What’s the status on SCA support for the the official Square extension for OpenCart? It’s written by iSenseLabs, presumably funded by Square. iSenseLabs seem to be in denial: “We haven’t receive an update on this topic from Square yet”
If SCA support isn’t forthcoming, ourselves and many others will eventually be forced to use another payment provider for which there’s support for a SCA compliant plugin. More on SCA and the December 2020 deadline.
