Ik ben mijn speelijst kwijt.

Hi @Ab van der Neut you can recover any deleted playlist following the instructions on this link: https://support.deezer.com/hc/en-gb/articles/115003736489-Recover-a-Deleted-Playlist
I Have checked your account in our system and in case you are referring to a playlist called “appie”, I can confirm that it is there in your profile.
Could you please log out from your Deezer app and login again with the email and password linked to your account, and let us know if that works for you?
Thanks :)
