After installing out-of-the-box LibreSpot 8.2.108 (from the standard repo) on out-of-the-box LibreElec 8.2.3 (Kodi Krypton 17.8), everything worked fine. After a reboot the device is not discoverable. By using the Kodi GUI My Addons -> Services -> LibreSpot en selecting "update", the service seems to be started again (even though I 'updated' to the same version). I have to repeat this every (re)boot (which I find quite tedious).
