Fortigate for Azure - Hub and Spoke

I am working on setting up a hub and spoke with an Fortigate for Azure deployed in the hub. I have been on the struggle bus for the last day trying to get it working. I have the vnets created on both the hub and spokes. The hub/Fortigate I am able to access and administer it via the GUI/CLI. I have created the vnet peerings between the vnets as well as the default routes to the Fortigate internal interface from the spokes. I feel like I may be missing a step as I cannot get the spokes to talk to the hub and vice versa. I have created the NAT and Firewall policies and I cannot get RDP to work to my VM for testing. I also am unable to ping anything from the Fortigate/HUB to the spokes.

Any ideas or should I reach out to support?
