Spotify playlist iframe embed doesn't update

[saaduu22]

My Question or Issue:

Im writing a small app that updates a playlist, I can see it working fine when I access the playlist through the spotify app, so the playlist is being updated. But when I load a webpage where I've embeded the playlist, it doesn't appear to be updated.

Even when I use the open URL, I see the unupdated version. Is there anyway I can force the embed to update? 

Thanks
