I have experienced issues on my Quintus:
The bluetooth gui does not see my headsets when searching for devices. But I can directly pair them using bluetoothctl and their hardware identifier.
After having done this, they seem to stay saved in the list of paired devices, since they auto connect from then on.
Yet, the quintus does never show the headsets in the GUI (one are Volla buds, the other is no name).
The Pinetime in contrary works without issues and is always visible in the list.
I can't remember having these issues before which makes me think that is connected to Noble.
My phone is running UT natively, no dual boot.
Maybe this can be added to observations made on Noble that might be addresed at some point.
