Impossible to add someone to a daily mixed playlist

[Sissou83]

Hello

I share a daily mix with a friend and I would like to add a third person to ít.

When I create the link to add a new member the link always returns an « expired Link » to that friend !! 
I do précise that I’m not talking about a collaborative playlist but the daily shuffled playlist

Hey @Sissou83 welcome to the Spotify Community! 🎵

Your daily mix is one of your personalised playlists. This means when you share a daily mix to a user A then the user A will see it with their recommended songs and not yours. As of now, daily mixes cannot be converted into a collaborative playlist either. 

However, you can create a copy of the daily mix playlist and then share it. This will not change the song list based on user recommendations. 

Make sure to check out blends as well. They are another type of shared playlists but with a taste match feature. 

Let me know how it goes. 🙂
