Thank you so much.  I commented out my basic:ANY rule in our AttributeFilterPolicies and my IdP initiated SSO test worked as expected.

That would happen anyway, that's what ANY means. There's no meaningful difference between IdP initiated SSO and any other unsigned request.

Yes, it is. Your policy won't work because your default applies also. All of your SPs are receiving the same superset already.
