          Warning! JWTSessions uses in-memory token store.
          Unless token store is specified explicitly, JWTSessions uses Redis by default and fallbacks to in-memory token store.

          To get rid of this message specify the memory store explicitly in the settings or make sure 'redis' gem is present in your Gemfile.
