Refresh the page fully
Use a hard refresh so the browser requests current files rather than its stored copy.
Open a private window
Compare the page without the normal browser cache and signed-in extensions.
Check another device or connection
This helps separate a local cache from a wider delivery issue.
Confirm the exact URL
Old bookmarks or similarly named files can point to a previous version.
Send visible evidence
If the old version remains, provide the URL, device, time and a screenshot.
Important
Avoid clearing saved passwords or all browser data unless you understand the impact. A private window is a safer first comparison.
