The Shopify agent has offered to run a resync process in the backend. It’ll take 4 hours and hopefully this will resolve the problem. I’ll provide an update if this removed the ‘issues’ from Semrush.
Response from Shopify Agent:
"..as part of the troubleshooting steps, what I can do here is to run a sync process on the back-end of your site to make sure that all is sync in your admin and your website. Please be assured that this will not affect your website and will remain active. Would you like me to proceed with this?
Also, this re-sync process will take 4 hours to take full effect. Please let me know if you would like me to proceed with this."
