If the the_preview hook does not seem to be working as expected, it may be due to conflicts with other plugins or themes that are also modifying the previewed content. It is recommended to deactivate other plugins and switch to a default theme to troubleshoot and identify any potential conflicts.

When using the the_preview hook, it is important to consider the impact of the modifications on the overall user experience and the consistency of the website’s design. It is best practice to test any changes thoroughly and ensure that the previewed content remains accurate and representative of the final published post.
