Without a repro it is difficult to say what might be going on. There are no changes in this area that I know of. But check that the function is actually owned by dbo.

This repro works for me:

CREATE USER pelle WITHOUT LOGIN

go

CREATE SCHEMA schema1;

go

CREATE SCHEMA schema2

go

CREATE FUNCTION dbo.somefunc(@d float) RETURNS float WITH SCHEMABINDING AS

BEGIN

RETURN log(@d)

END

go

CREATE VIEW schema2.viewB AS SELECT dbo.somefunc(1E0) AS col

go

CREATE VIEW schema1.viewA AS SELECT col FROM schema2.viewB

go

GRANT SELECT ON SCHEMA::schema1 TO pelle

go

EXECUTE AS USER = 'pelle'

go

SELECT col FROM schema1.viewA

go

REVERT

go

DROP USER pelle

DROP VIEW schema1.viewA

DROP VIEW schema2.viewB

DROP FUNCTION dbo.somefunc

DROP SCHEMA schema1

DROP SCHEMA schema2
