Thanks for the info. I did try switching off and on the device. Did not work.
Before I delete and re upload the Spotify app, how do I find all my accounts? I appear to have made two accounts. The original that I have Spotify premium and have on my iPad but can't remember details for and anew one which does not have premium Spotify and I cannot access my downloads on. I do not want to delete and not be able to access all my downloads. My original account has the music for my Engagement party which is in 3 weeks!
