My Question or Issue
I have successfully added tracks to one of my private playlists through the web-API. I get a 201 and a snapshot ID in response and if i go to the playlist in the browser i can see the updated tracks. However, if i go to the playlist on Spotify Android or Spotify Linux App the playlist is empty. If i reinstall the apps, both on the phone and computer, I can see that the playlist contains the tracks I expect. I'm creating an app for myself that updates this playlist everyday and reinstalling spotify in order to do this is just ridiculous. If i manually add a track through the UI, either on the phone or linux app, the playlist is updated everywhere.

Am i missing something or is this a bug?

Kind regards,

Simon

I am facing a similar issue. I have many playlists and one of it is P1.
i use playlist api to get all the playlists and in that response, P1 has snapshotId as S1.
I now add a song to P1 and i get correct response of 201 with S2 as snapshotId.
When I use fetch api again, I am getting P1 with old S1 snapshotId. But the totalCount is updated correctly.
