I was normally listening to my playlists in Spotify, I stopped listening for a few hours and I went back to the app but this time offline without an internet connection but I came across my playlists all downloaded but were unavailable to access and listen, App and I closed the background, I connected the device to the internet and I went back to the app, then started to download the songs and / or playlists all again and I did not remove the downloads, it is the second time that this happens to me by the last I did not have a lot of downloaded songs so I downloaded it again, however, this dps has downloaded more than 3 thousand songs and it simply self-removed and started to download again, I'm really frustrated with what happened and I know there's no other solution but to download everything again But I do not want it to happen again.
Would anyone in the community know why this occurred?
