The same thing happened to me with .11 when I selected an upgrade channel. I was able to get the functionality back by deleting the xml settings file for the addon.
It was in one of these.
.\Userdata\addon_data\service.openelec.settings
.\Userdata\addon_data\service.libreelec.settings
Very , very grateful for your help , will give it a try .....
