have noticed in webmaster tools that one of my sitemaps is showing 0 discovered url's. It's been like that for weeks, not sure what may have caused this. Unsurprisingly all sales have dropped off.
/sitemap_index.xml Mar 25, 2020 May 30, 2020 Success 6
/shopping?pto_sitemap=xml Mar 1, 2020 May 24, 2020 Success 0
Any suggestions would be appreciated.
