All songs in library suddenly gone

[Svavare]

Hi,
My whole library was empty on the morning of 7:th of april. Playlists were gone too.

I could bring the playlists back with the feature on the homepage but more than 1500 songs are still missing. 

It must have happened the 6:th of april - the playlists were deleted then.
I use android 8.0.0 on a Sony Xperia XZ (F8331) Spotify 8.4.49.462 armV7 and android 6.0.1 on a Samsung Galaxy S5 Neo (SM-G903F) Spotify 8.4.43.632 armV7
Already tried a relog but it didnt change.

Please help, took me years to collect the songs!
