I have just joined Spotify and I am running a free account. On the Android app the artists list has the 3 artists I picked upon starting the app for the first time, since then I have added lots of albums using the heart icon. On the desktop version the artists from those albums now appear in my artists list - which is what I want. But on my mobile they aren't in sync and just show the 3 original ones.
How do I get them in sync?
