The Editify link isn't showing in the actions dropdown
This is most likely due to the order being over 60 days old.
Shopify recently introduced a new change which stops 3rd party apps from accessing orders from your store over 60 days old.
Thankfully, Editify has been reviewed by the Shopify team and has been granted access to older orders.
To proceed with editing orders such as this - please log back into the app and accept the new permission.
