I tested it on 3 different devices and it's working fine. Have you tried it on an incognito page to double check?
How to activate an Incognito web page varies from browser to browser, so it's better to search on google.
Therefore, if you're using Safari, google for "how to use incognito on safari"
If you're using Google Chrome, google for "how to use incognito on Chrome"
and so on and so forth.
