A conditional rendering might not work in the Experience Editor. When switching personalization conditions, the content does not change. There are no errors in the log files and in the browser's console.
To resolve the issue, consider one of the following options:
Be aware that the hotfix was built for specific Sitecore XP versions, and must not be installed on other Sitecore XP versions or in combination with other hotfixes. In case any other hotfixes have already been installed on a certain Sitecore XP instance, send a request for a compatibility check to Sitecore Support.
Note that the ZIP file contents need to 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.
