Years ago, I only followed a dozen or so accounts, & they appear in my 'Following' section & feed in my Android app. But recently I started following another dozen or so accounts, & they don't appear in either my feed or under the 'Following' section in the Android app. However these new ones do appear in both my feed & the 'Following' section when I access SoundCloud on my desktop.

Today when I started the Android app it returned a login error. After re-logging in it worked properly.
