Been having this issue with trying to enable Spotify to download songs with mobile connection and not just wifi. The problem is that, that specific settings is grayed out, a long with loads of other settings on my phone. This is really frustrating because of songs I want enabled offline. I always need this option from time to time, like before flights (I fly a lot), and other situations.
Yes, I have tried restarting the app.
Yes, I have tried reinstalling the app.
Added attachments of grayed out settings.

While your phone is connected to another device (wafflesaurusrex in the screen capture) all the options which aren't relevant to playing through connect will be greyed out. Switch play back to your mobile and all options will be available again.
