I have found this official Shopify tutorial:
It seems to suggest that you can now edit product Metafields via the Shopify admin without the need for an app which sounds great but when i try and follow the instructions i don't see any of the links / options it mentions in the admin.
Am i missing something here?
Hope you are doing great
For this you would need an app as say in the tutorial
Previously metafields could be added using API calls, so an app was required for merchants to work with them.
I recommend this app to do so: Metafields Guru
