I have a theory that I found a bug/error because it happened to me for the 3rd time already.
So, I was using Spotify then I restart my phone (other app recommendation) without turning off Spotify. After restarting the phone, I stumble upon my downloaded albums to play again what I'm listening earlier. My downloaded albums are now tagged as not downloaded. I checked the file folders and it's deleted but it's still there.
I think the cache for downloaded songs are broken upon shutting down the phone. Now, I need to reinstall Spotify to delete those useless files because of broken cache.
This was just a theory of mine. But if it's the true reason behind this downloaded songs turning to not downloaded, I think they must fix this cache handling upon shutting down to avoid error.
Well it's not a problem for me to download again this songs (8GB songs) but it's just a waste of a lot of bandwidth and time tbh. As I said this is the 3rd time I'm experiencing this issue and reinstalling Spotify is not a solution.
Asus Zenfone Selfie (ASUS_Z00UD)
Android v.6.0.1 (Marshmallow)
Spotify v.22.214.171.1242 armV7
Solved! Go to Solution.
If you encrypt your SD card, the card takes longer to mount and starting spotify too soon after powering your device on can result in the cache not being recognised. Check out Spotify's fix in this bug topic.
