I was not able to connect, so I have edited style.css file of the child theme via File Manager plugin on your site, this https://prnt.sc/x6paSnSkqdt4 was changed to https://prnt.sc/dQCNm71hbkCa . Please check your site now, the child theme is activated and it works with the latest version of the parent XStore theme.
Go to WooCommerce > Status > Templates, messages about outdated files have disappeared.
