Doesn't update playlists that already exist

[KSu42]

I've noticed when trying to run this after updating my spotify that it doesn't add tracks to the playlists that already exist on deezer. Is there any way you can implement this? Or if it's easier, an option to delete all playlists from deezer to allow the updated playlists to transfer properly?

My intent is to run this script as a Cron Job every day to keep my playlist synced among different services. With this issue, unfortunately, I cannot.

Any plans on implementing this?
