Hi AndrewMcN_SFRS​, thank you for the detailed write-up on your issue. I'm a PM on the MCC team and would like to learn more about your environment and try to get you unblocked. 

Can you please re-post your issue to the MCC Tech Community forum (Microsoft Connected Cache for Enterprise and Education | Microsoft Community Hub) so that we can make this visible to other MCC customers as well?

We can continue the discussion there.
