After a change is published to your site, you may still see the old version of the page in your browser.
Why this happens. Browsers keep a saved copy of pages, styles, and scripts, and can keep showing that saved copy for some time after a change is published.
What you can do. Before reporting that a published change is not working, open the page in a private or incognito window (Chrome: Ctrl+Shift+N, Mac: Cmd+Shift+N). A private window does not use the saved copy, so it always shows the current version of your site.
If the problem is still visible in a private window, it is real. Send support the page link and a short screen recording of the steps. A recording lets support see exactly what happened on your screen and resolve it much faster than a description alone.
