After the installation, I have got an error
{{#pageTypeNonce}}{{#webpackChunks}}{{/webpackChunks}} {{/pageTypeNonce}}
Also, the child category product is displayed but the main category product is not displaying kindly check the below image
Also when we go to the product detail page again we are getting Oops!
Looks like the page you were hoping to find doesn't exist. Sorry about that.
Try install module - Swissup 2 UPWARD connector module
