Spotify automatically removing saved offline music

[cbvandine1]

I have noticed on multiple versions that I will save a bunch of albums for offline and then a few days later they have either all disappeared or there are only two or three songs in the album. Is there any fix or am i the only on experiencing it? It so far has only affected my saved albums. Saved playlists are all left alone. It started on my old phone (Moto Droid Turbo 2) and has since carried over to my new phone (Google Pixel XL) Any help would be awesome.

Thanks!

(Spotify Version is 8.4.3.479 armV7)
