I am having the this problem for weeks now! I have tried all the suggested fixes like doing a clean reinstall and changing the APN for T-Mobile but whenever I try to use Spotify using Mobile Data, I always get the message "No Internet Connection".

It's really irritating because I used to always listen to suggested playlists everyday, but I cannot do that anymore.

If it helps at all, I have an Xperia Z1S with T-Mobile as my carrier (and yes, I tried the APN thing already and it did not work). Running Android 5.0.2. I am also paying for Spotify Premium, and the version of Spotify on my phone is 4.2.0.739

Hopefully this could get fixed soon. If I get charged for my next month with Premium and this is still a problem for me, I might switch to an alternative. I really hope that that would not be the case because I was very happy with Spotify before this happened.

Thanks
