Favourite songs disappear after re-download of the app

[Lara_me]

Hi team!
I recently had to uninstall and re-install the Spotify app due to some problems with the activation of my family premium abo. This is fixed now, however after the re-download my app seems to be at an older version meaning that all my favourite songs (songs I marked with a heart) disappeared from that list and only songs that I liked a few years ago are in there.
I tried re-installing the app and deleting the data and cache a few times, but nothing changes. Since it's not a playlist per se, I cannout recover it as I could with a deleted playlist. So all my favourite songs are gone which is a real bummer!

Can you please help?
