KDE Connect has lots of bugs with... connecting.

But when it works it's great. P2P over lan.

I never have connection issues; it's been one of those always-reliable tools for me. Can I ask what bugs you experience?

on every OS - windows, linux, android, iOS - it's like a 20% chance that it will connect or send the file if one of the clients has closed and reopened or disconnected momentarily. you have to close and reopen both clients.

Exactly my experience. And not exactly intuitive either.

Has a ridiculous number of bugs and is quite unreliable. Trying to talk to the devs usually goes nowhere.

It's ok but it won't let you copy multiple files at once on Windows
