I use Spotify (1.045.186.g3b5036d6) on Mac (macOS Sierra Version 10.12.2) and I use Spotify (7.4.01643) on my iPhone (iOS 10.2.1) and I don't receive any notifications. Look at my settings:
 my settings online
- my settings in the Spotify iPhone app
 my notifactions settings in my iPhone settings
A long time the notifications on my iPhone and notifications via email worked. My email address is still correct. Today I turned on the notifications of „recommended music“ and tada I received an email today . But still no notifications of new releases of new bands that I follow .
Can some one help me? Thanks. 🙂
