Spotify keeps deleting my downloaded music

[Amydoh]

Hello everyone,
The music I have downloaded on my phone keeps on un-downloading itself from my playlist, so I log on offline and have no music available to listen to. While this isn't a massive problem when I'm on the go in Holland (where I live) I'm headed abroad for 2 months soon and would really like to make sure it doesn't happen whilst I'm there.
Also, since I can only download to 3 devices, Spotify counts my re-downloading as a new device and then proceeds to remove all music from my tablet too!
This whole procedure occurs about every 2 weeks and I'm getting fed up of it now. Im not very tech-savvy so easiest explanation possible if you can help me please.
Thanks in advance!

Hi. It sounds like your SD card keeps unmounting possibly because it is faulty or because it's not making a good contact with the phone. The quick solution is to remove the SD card, reinstall spotify and use internal storage for spotify.
