On iTunes Apple Music keeps cutting 'on/off' for Adding or downloads (just for Adding or downloading, everything else like playing, Radio, Connect,... all work). While 'off' I can't Add or download any music. You can see this by looking at Added music that has not been downloaded.It will often be grayed out and then I can't Add or download any Music. Other times it will be normal (black) and I can Add or download. Does anyone know how to keep iTunes/Apple Music 'on' and not going to 'off' grayed out?
