AnyConnect SAML slow to establish connection

Running into an issue with AnyConnect and OKTA SAML with 90 second delay between authenticating and actually establishing the connection.  Initial login/redirect/MFA is quick then the client shows "establishing connection.." and 90 seconds later (give or take) the connection establishes and user can pass traffic.  

DART logs show the below which clearly shows a long delay between "Retrieving device details from cache" and "received VPN session Configuration settings."   14:23:14 > 14:24:54 or right at 90 seconds.

Note we have other profiles not using SAML that have never had this issue so I simply not sure what would cause this.   Logs on OKTA side show everything happening within a couple seconds so I attribute this to something on the ASA/FP side but what I don't know.

I had the same 90 second delay loading details from cache issue.  However, we were using RADIUS back to an NPS server.  Enabling dynamic authorization and interim account update resolved our slow connection time and it now connects in seconds versus the 90-120 seconds it took before.  Not sure if that will help in your case though.
