No caching plugin installed | browser developer level network caching disabled | nevertheless changes to the site delayed by hours

As you can see in the picture, I have not installed a caching plugin.

In the browser, both the current Firefox and the current Chrome, the changes in the frontend are unfortunately only visible to me hours later, even though I have also deactivated the caching of the browser developer level (F12) under network analysis.

EDIT: I have already cleared the browser cache (both Firefox and Chrome) many times with CTRL + Shift + Delete, but unfortunately pressing the F5 key does not help.

EDIT 2: I have now also added the IP and domain of the page to be edited to /etc/hosts and deactivated OPcache. (I didn’t even see the deactivation of the OPcache live via phpinfo(), I had to confirm with the server center and it was only several hours later that I was able to see it myself.)

So neither the browser nor the website itself should cache anything, or have I forgotten something?

Since I use the normal web space from All-Inkl.com, there is certainly no caching involved.

Solution found:
Firefox > Developer environment (F12 key) > Applications > under Service Worker, end the Service Worker entry
Chrome > Developer environment (F12 key) > App > under Service Worker, end the Service Worker entry
