Help needed to test Spotify plugin with Oauth

After a fresh install on a new image I finally had this working last week.

However, now I am getting an Unauthorized error:
… An error occurred while listing Spotify new albums WebapiError: Unauthorized
… info: An error occurred while listing Spotify featured playlists WebapiError: Unauthorized
… info: An error occurred while listing Spotify categories WebapiError: Unauthorized

Logout and new connection didn’t solve the problem.

How do I fix this?

@Pierre: the pagination issue is addressed in this thread: https://forum.volumio.org/spotify-playlist-only-items-are-shown-t10296.html

EDIT
Datetime was not properly set on my device. Looks like procedure spotifyCheckAccessToken needs a proper datetime. After setting it and disable/enable plugin the problem is solved for now…
