Why the product comment widget doesn't work?
It shows some info, but the comments aren't listed out.
1. Your site is probably under maintenance, and you didn't add your IP to the whitelist. Adding your IP to the whitelist can fix the issue.
The issue exists with quite a lot of Ajax requests. Although the Enable store for logged-in employees is enabled, it's still recommended to add your IP to the Whitelist.
2. Another possible reason is that two product comment widgets were added to the same page. It's common to display the product comment widget in a tab on the Desktop version and display it in an accordion on the Mobile version. Don't add the product comment widgets twice; the Tab & megamenu widget can switch to an accordion layout on the mobile version.
