Max Control theme is high dynamic them like itself is a system. The theme built to allow customization flexibility to the user without touching a single line of code.
To provide dynamic control it is calling many Question2Answer core files and in some part of the core files it doesn't allow to interact with the SSO or WordPress integration. So eventually when Max Control theme used on SSO setup it will miss many dynamic files.
Not giving any commitment but in future version will try to support SSO as well.
