I have recently replatformed from a custom PHP build to Magento 2.2.4, during the go-live process we changed from www to non-www versions of the site. I've updated Search Console to make the preference to the non-www version of the site.
Now I'm getting the following notice:
Magento is using a stock version of the robots.txt file as seen here current robots.txt
I also verified that the site has Index,Follow enabled.
Does anyone have any thoughts as to why this maybe occurring?
