For amusement now; my ticket at Enphase is still being updated and telling me that there was never an issue; and that “The data from the Enphase Consumption meters would only be visible on the Enphase Enlighten App/Website portal.” despite having mentioned consumption API multiple times in all my responses. They even typed a lesson up for me on how to read the enlighten app (Which was never broken) - I suspect if anyone else has logged a general support ticket with enphase they would have been given a similiar runaround.
