Firmware upgrade for FortiWeb WAF Azure VM

Hi,
Im trying to obtain firmware for my FortiWeb WAF Azure and AWS VM, which is on a PAYG license.
The FortiWeb is registered in FortiCloud and shows as one of my assets.
When I go to Firmware Download section and select FortiWeb as my product, I get a message indicating that I do not have a contract for this product?
Opened a ticket with Support and first they said, with a PAYG license I can download firmware from Azure/AWS market place, with a link directing to the page when you want to purchase and deploy a FortiWeb VM. Not the actual firmware to upgrade my current FortiWeb.
After pointing this out to, support came back and said I need to go to VM images, select my product and download the image, but when I follow those steps I see that these images are for New deployments and not for firmware upgrades.
Can someone please indicate where I need to go to download my firmware, and is it possible that there might be some sort of registration issue with my FortiWeb? It does show that its licensed and registered for support on the FortiWeb GUI.
