When adding a new product to the existing category in Sitecore Experience Commerce scaled environment, a new product appears in the category listing but the product details page might not be accessed in a storefront. The root cause of the issue is that the date of the entity update and the date of the mapping update are compared between the local time and UTC time formats. As a result, the date comparison is not correct, and subsequent processing is not indexed, mapped, or cached for the entities that would otherwise be updated.
To resolve the issue, consider one of the following options:
Be aware that the hotfix was built for a specific Sitecore XC version, and must not be installed on other Sitecore XC versions or in combination with other hotfixes. In case any other hotfixes have already been installed on a certain Sitecore XC instance, send a request for a compatibility check to Sitecore Support.
Note that the ZIP file contents must be extracted to locate installation instructions and related files inside. The hotfixes must be installed on a CM instance and then synced with other instances using standard development practices.
