Hi there!
 I have a strange issue here. For some reason every time I close this app it logs me out and deletes all of my music saved for offline use. It's obviously pretty annoying, because the offline was a big seller for me to keep spotify because I don't have data on my phone. Only WiFi use.
 It only seems to do it when the app is on my SD card for some reason. I would move it back, but I put it on there so I could use the SD space for the offline music. Internal memory isn't great on my phone.
Oh, and I should add that I have reinstalled the app on my phone, restarted my phone, and have deleted all of my offline devices and reset my phone as one. No change.
 Any ideas as to why this app would be behaving this way?

My phone is a Moto X Pure, running Android Version 6.0.

Cheers,
Ryan
