I was just told I have several pages with Robots Meta Tag, X-Robots-Tag that must be removed to have these pages appear in Google or any search engines. I was told " If you find any pages that are blocked unintentionally, remove the existing Robots Meta Tag, X-Robots-Tag or robots.txt file directive that is currently in place." How is this done?
You can modify your robots.txt.liquid template file.

It’s not available by default but is easy enough to create.
