Comment 1 Stefano Crocco 2022-05-15 14:17:32 UTC 
That's not completely Konqueror's fault. The problem is that web.whatsapp.com checks which browser you're using by parsing its user agent string and infers, incorrectly, that you're using a version of Chrome which is too old and asks you to upgrade.

There's no way for Konqueror to fix this issue, except by changing its user agent. However, doing so risks to break some other site. The best approach would be to make the user agent configurable depending on the site, as it was with the previous web engines (KTHML and KWebKitPart). Unfortunately, the current web engine, QtWebEngine only allows to change it globally.

I'll think if I can find some kind of solution, however.
