I created Gatsby.js website hosted by Gatsby Cloud(Individual Trial Plan) and using Contentful. Although I didn't set Robot.txt, the production site automatically had x-robots-tag: none at HTTP header. This caused Google Search Console to show error 'noindex tag is added'.
Could you kindly help me how to remove x-robots-tag: none and set x-robots-tag: all.
I have already tried to use proper robot.txt with gatsby-plugin-robots-txt but never solved.
