I have two BBC Sounds accounts that I use mostly for testing, but I get very different results on four different apps. If I go into it then Discover Podcasts (or Music You’ll Love):
iOS: works 100%
Android: works 100% but dates are missing from podcasts (just shows length in mins)
Windows Desktop: “Unable to browse music” for both list types (all others work)
play.sonos.com: BBC Sounds not even listed as a service.
Of course I tried my own apps and I get similar results to the official Windows app (due to empty xml being returned). Can someone located in the UK try these and compare results?
