Good day,
It has been some time since my last renew, thing to confuse tho, when you have credit info in your profile, and click the box, as it said, payment will be dome or something.
Then, I found to complete the issue, need to see your invoices to complete it, as these steps:
1 - New Purchase, then select, then "mark" the box to complete the (when I tought I am done)
2 - Your Invoices - Pending - (Pay Now).
SO, what the point of step one "mark":
My best
