Cannot add music library to Soundtouch app
I am having problems adding my Windows Media Player library to the Soundtouch app. I click through the menu to add music library on computer, select Windows Media Player library, click add, but nothing happens. It takes me back to the front screen of the app (showing internet radio stations, etc.) but when I go back into the menu there is no music library available. If I go to settings, music services, music library on computer it just shows "you haven't added any music libraries yet". I am not getting any error messages, simply nothing is happening. I have made sure all the streaming options in WMP are allowed but still nothing.
I have tried everything I can think of - clearing WMP library and re-adding, uninstalling and reinstalling the Soundtouch app, remove and re-adding connected speakers, but nothing seems to be working.
I am running Windows 10, with WMP v.12. Soundtouch app v17.170.80. There are 3 speakers connected to the system (working perfectly for internet radio!), 2 10s and 1 20.
Please can anyone help as this is becoming very frustrating!!!
