Google Search Console Errors After Upgrading to Joomla 4

-- url of the page with the problem -- : www.classicalguitarhowto.com/
-- HikaShop version -- : 4.6.1
-- Joomla version -- : 4.2.2
-- PHP version -- : 8.0

The client site was upgraded to Joomla 4.
Within a week there were numerous Google Search Console errors. In particular are ones about RSS and ATOM feed URLs.

The category that Google has them in is: "Duplicate without user-selected canonical"

Here is an example:

Hi,

The error with the RSS/Atom feeds is a bug in HikaShop linked to Joomla 4. Updating your HikaShop to the 4.6.2 will fix the problem.

However, this is not linked to the "Duplicate without user-selected canonical" error. This means that in the category of the page, you didn't enter the main URL you want to be indexed for the category and that the category can be accessed from different URLs.
So for the URLs with these duplicate errors, you need to enter a canonical URL in the settings of the category and ask Google to recrawl the URL.

Thank you.
