Unfortunately the integration is really quite weak with Apple. KDE Connect cannot remain active while the application is not in the foreground. It’s possibly a packaging issue but pairing from fedora is also quite flakey.

As absurd as this sounds windows -> iPhone via their phone link is actually almost as good as apples built in ecosystem to the point where I can make phone calls and send texts on my computer. It’s not quite as seamless especially the setup but that is a well done wizard and it mostly works.
