  2. Select Plug-ins -> Installed Pluging
  3. Select Spotify and sign in / sign out
  4. Click on Authorize button
  5. Observe web page saying “oauth-performer dfs volumio org didn’t send any data”

Additional Information

Today (2020 June 24) search function of the Spotify plug-in stopped working. It produces “no results no items”. I then signed out and in again to my Spotify Premium account in the Spotify 2.0.2 plugin. Sign in goes well but Authorize button produces web page saying “oauth-performer.dfs.volumio.org didn’t send any data”. As a consequence Spotify is note available any more on Volumio.
