Playlist cover updated via the API has a delay of hours before updating

[Andrew2211]

Hello,

Our app creates and updates playlists on Spotify using the public API.

Recently, one of our users complained that the playlist cover was not updated after he updated it from our app. After a couple of hours, he checked and the new cover was updated.

Any ideas why this happens? It does not happen all the time. Could it be cache related or the API does this on purpose?

Have you tried testing through an API client like Postman or Insomnia? Or even simpler, testing through the API docs?

I just tested it through the API Docs page and it updated instantly for me. If it does for you, as well, I'd imagine it's a caching issue and not something on Spotify's end.
