I registered Yellow card early this year, but the KYC took forever to be verified. Abandoned as we speak.
Is this a one off or you know people that had similar issues? Did you try to reach out to their support team?
This is my personal experience, don't know if it's a general thing or just me but I can tell you for free, the whole KYC process is done manually. I got verified after a long wait. I logged in after this topic and got a pop up message to " input my BVN number" before I can make deposit.
