vWAN Active/Active - Access to FortiManager dropping

HI All,

I understand the Fortigate vWAN offering runs in Active/Active with FGSP sharing the sessions over both NVAs. This is not an issue for most traffic however, when trying to access Fortimanager from inside an Azure vNet it kicks the session out after about 20 seconds..I believe this is because the source public IP is changing due to the Active/Active setup, this would be the same for Banking etc... Other than putting a UDR in to bypass the NVAs what are the other options? Is there any changes within vWAN that can support an Active/Passive setup?
