Import Logic Apps (Standard) into Azure API Management

Hi there

I have followed the approach described in the blog to setup My logic app standard with API Management. I've just secured my API management with AD B2C authentication. Since doing this I now have two authentications for both API management and one that comes out of the box with logic all (sig). 

When I put a valid token in I get this error:

"message": "The request has both SAS authentication scheme and 'Bearer' authorization scheme. Only one scheme should be used."

Is there any approach to solve this conflict. All the policies I've seen for handling authentication with logic app are based on the non-standard. I guess the question is, does Secure API Management support Logic App standard?
