Bluetooth not working after resume

I have on my Lenovo Yoga two Bluetooth devices connected:

  • Mouse MX Master
  • Logitech Bluetooth audio adapter

When I start up the laptop both are connected. After resume the laptop from suspend the mouse is working but not the audio adapter. When I click on the Bluetooth icon in the KDE system tray the pop up show “No devices found”. I can get it back to work when I restart Bluetooth using the command “systemctl restart bluetooth”. This behavior is since January before it was working properly. Do I have probably to delete (reset) all Bluetooth settings? If yes, how can I do it?

Thanks in advance.
