Of course, I have always cleaned, both the Joomla cache and the JCH-Optimize cache. Maybe you saw the changes immediately because the server uses Redis and for you it created a new session, while for me it continued to use the one already there.
I have now reset everything and on Brave I see the changes, on Chrome and Firefox I don't, even though I have already cleared their caches.
OK, Paul, I see the changes now too, thanks!
Sorry to have wasted your time with a problem of mine, local. However, I hope that others reading this post will find a solution to their similar problem, without having to ask for assistance.
