Me again (see this post), still having a lot of problems with Spotify and the SD card: nothing is solved and I still lost regularly the SD card storage. It is absolutely not usable!

But now I have a few more information:

- I know why the "storage" entry disapears from the settings menu: because the Spotify folder on the SD card is locked! I tried once to clear it and I could not access it. The folder is just not accessible.

- I also know how to reproduce my problem with 100% of success: I switch on the Wifi, select to download all titles and the background process starts. Then I leave my office/home and of course lost the Wifi connection: I got either a message telling me that the download has failed or Spotify just crashes. Then, in both cases, I have no more "storage" entry in the settings menu. I have no other choice than restarting the phone to get it back. But "of course", Spotify does not use any more the SD card and if I switch it on, it is not even able to get the available content. Back to the starting line 😞   

It is really, really annoying, beleive me, because I cannot listen to music in my car by simply using the data connection: I lost regularly the network, the music stops, it make some interference with my car system, etc. That is fore sure the problem of leaving in a wild part of France (Cote d'Azur) and using a low cost provider (Orange pro).
