Thank you for your reply and the screenshot you shared, normally this preview window is there, it may be that there is an exception in your current account profile, we suggest you can refer to the thread below to create a new account first to see if it is normal.

If the new account still doesn't have the preview animation, you can upgrade your system in place to install the latest version first.
