Installed this morning ...... rebooted ...... tried 'Add Device' without turning on any new device ..... made my phone discoverable and IMMEDIATELY it popped up in the window.
The update also provides connection options ..... DUN, Send Files and No service setting ........ selecting the No service allowed me to browse the contents of the phone.
So it appears to be functioning properly .... as much as I use it anyway.
I don't use the DUN service so have not checked that.
This appears to be the solution for the connection troubles that I, and others, have had with KDE bluetooth.
