LinkManager might render incorrect Storefront URLs for related product items. The issue happens when products are associated with more than two catalogs or storefronts.
To resolve the issue, consider one of the following options:
Be aware that the hotfix was built for the 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 hotfix must be installed on a CM instance and then synced with other instances using standard development practices.
