I have installed Kde Connect into: dual boot desktop (Windows/Ubuntu), dual boot laptop (Windows/Ubuntu) and Android phone.

The problem is that both computers keeps themselves connected to the phone without problems, but when I try to pair both computers (desktop and laptop) it works for some seconds and then unpairs.

I have also noticed that them unpair by clicking Update.

Thanks.

can you elaborate on the issue a bit more in a bug report at bugs.kde.org ?
