Cannot manage Spotify playlist

[TheOldPresbyope]

I guess I still don't know what to expect. I just did a test with four Spotify apps connected to my moOde 7.4.1 player:

• Spotify Web app in Firefox on my Linux Mint laptop.
  
• Spotify for Linux app on the same laptop
  
• Spotify app on my iPad
  
• Spotify app on my Android Pixel 3A phone.
  

When I create a playlist and save it on my iPad, it shows up in all apps. I can load it and start playing from any app. All the apps call out the currently playing track one way or another, say in the left column or in a bar on the bottom of the screen, and the call-out can be selected to make it full screen.

Only two (Spotify app on iPad and Spotify Web app on laptop) highlight the currently playing track in the playlist in green and with an animated bargraph.

From the Spotify app on my Android phone I can open, edit, and save the playlist and the change shows up in the other apps.

The thing is, I see similar behavior if I select one of these apps as the player instead of moOde.

Taken altogether, I don't see a librespot issue.

Always willing to be shown to be wrong
