I have had the premium Spotify account & my Bose Lifestyle Soundtouch 535 working for nearly a year. The recent update has stopped this. Both applications are the latest versions.
Using the Soundtouch app on my iPad the Internet Radio works fine and also TuneIn. But when I try to use the Spotify, all I get after I select a song to play is a blue screen with the word Loading appear.
The Spotify app on the iPad doesn't work anymore with the Soundtouch. It plays through my smart TV and even in the iPad. I try and switch the output to the Soundtouch and it becomes silent.
I have reinstalled both apps, made sure we are using the same network settings but no success.

Can't play it using my laptop anymore as well. Plays fine locally but not via wifi connection to the Soundtouch. 

Any ideas?
thanks
Vic
