I've noticed 2 issues:
1) Bluetooth not working yet. When I tried - I could not get into BT parameters screen (once I highlighted BT in Libreelec settings - the parameters window was empty, and also I could not exit the screen.
2) Netflix doesn't work, cannot be installed
On a good note:
1) FLAC music finally works
2) Does not crash when watching TV
