Monthly listeners count always zero


Monthly listeners count always zero

Casual Listener
EDITED: Just discovered that the problems was weirdly gone.

Hi, I don't know since when the monthly listeners count in an artist's page is always zero. I'm sure days ago it's correct with numbers displayed. The problem appears both on my phone and tablet. Did some searches but didn't find a second person having this problem.
Cleared app data, rebooted, reinstalled but no help.
Account type: Premium
App version: (phone and tablet)

Any ideas? Thanks in advance!
