Thanks, I'd assumed it was something I was doing!
Tidal ickstream outage
Guys, if your ickstream/Tidal is showing 'no content' in the directories and you can't play music, Tidal had an outage since midday yesterday. Info on their website. You may need to uninstall tidal service in ickstream, was a bugger for me but does sound great (maybe even better), now.
