SUMMARY

KDE Connect - Half second display recognition of other Android Devices show up underneath 'KDE Connect Devices' heading for half a second then disappear:


On any of the android devices, in the 'KDE Connect Devices' heading, to refresh the list either pull down on the screen OR goto the 3 dots menu, and select 'Refresh'
You should see the other PC-Paired Android devices's show for about half a second then dissapear on both android devices at the same time.

This happens *REGARDLESS* of wether one has one or both android devices paired to PC KDE Connect or wether the PC is turned off

Not sure if related but i see t his a lot but only on my machines with multiple nics, notably many whos endpoints do not include the phone.   But if multiple endpoinds include the phone with different latency then even weirder flashing of available unavilable availble happens. I always thought it was my weird network config but if there is a bug here then i can try to give more info as well

@lainlives - Thats appreciated :)

I think this glimpse of other devices is just another symptom of the same issue in https://bugs.kde.org/show_bug.cgi?id=501635
