SUMMARY

When pairing a device - in my case a headset Jabra Evolve2 65 - the bluetooth tray icon shows it as connected and I can disconnect it in context menu. When later I want to reconnect the device, then it technically works, but the icon still shows "unconnected" and in context menu - while the battery level of the connected device is shown - it is still listed as unconnected and shows me a "connect" button.

STEPS TO REPRODUCE
1. Pair a bluetooth device
2. Switch device off and on again
3. wait for it to connect itself

OBSERVED RESULT
Device is connected and can be used.
The icon still shows no connected devices.
When clicking the icon, the device list shows the battery level of the device.
The list shows no "disconnect" button for this device, but "connect".

EXPECTED RESULT
The icon should show one device as connected

bluetoothctl also shows it not connected, but shows battery level, just like Plasma does. So maybe this is an underlying problem not connected to Plasma?

Sounds like an upstream issue indeed.
