I am using a samsung galaxy s7 fully updated. I can only load tracks from spotify when the device is connected to wifi. If I use my network 4glte. I can still see the songs in my list but they will not load. I can look at other songs and search spotify with no issue. However the moment I choose a track to load. If i am not on wifi the picture of the track will show as if its loading then I get the message that I need to check my internet connection. I have a strong connection and even pay for unlimited data. I have also uninstalled the app twice. I have no trouble with the app when on wifi. But if I am trying to experiment with mixes elsewhere, unless I connect to a wifi source I can only use the tracks on my phone. My provider is Tmobile. I hope the image loaded because this is what I see everytime.
