Hi all!
I need to add a canonical URL to some pages in a collection (republishing a Substack). I followed some posts here to (1) Add <link rel=“canonical” href=“[canonical field]”> to the custom code in the header of the collection and (2) Add a text field to the page editor to pull the canonical url.
Looks ok to me when viewing page source, but no tools are catching it 
Any help is appreciated 
Page: Before There Was Money | EOM #002
Canonical URL: Before There Was Money - by wotterdog - Evolution of Money
