ADFS Proxy Replacement on F5 BIG-IP

I just finished configuring this and it works well as long as APM policies for Azure MFA are not enabled ( at least for me). When the APM policies are enabled, forms based SSO is not working, user name does not get pre-populated in the F5 logon page. Also, I am using the Azure Mobile app ( which requires the user to be enabled for 2FA in Azure). This presents a problem in that once the user has passed primary auth (AD) , secondary auth (Azure MFA) , SSO to ADFS, Azure presents the cloud 2FA again. When the F5 provides pre-authentication including Azure MFA, is the 2nd factor claim passed on to the ADFS server ( i have a relying party trust which will forward MFA claims to Azure thereby preventing the second MFA prompt from Azure)

Any help or suggestions on why SSO is failing would be greatly appreciated. I have configured exactly as per the deployment document.
