When I try to add the Meta field SEO.HIDDEN I get the error message that this namespace has already been taken - which it has not. I have this working fine on other sites but the theme Canopy is not allowing me to do this.
Hello @FableAds
This issue is not theme specific, it must be something else. You might be adding same namespace and key in metafields for any product.
Thanks for your reply. We only have a handful of metafields on this new
site. I checked all of them and seo.hidden is not being used anywhere that
I can see.
