When I go in my library -> artist and select one from the list, I enter in a page where is written the correct number of followers and the list of tracks/albums I "liked". But if I select the menu (upper-right corner) from that page, go to "Artist's page" then I go back, the number of the followers is set to 0 and it remains until I reboot the app. I have the last version of android app, some months ago this didn't happen. 

Is there any way to report this bug? Because after 2 months since I reported this fact via e-mail, the bug hasn't been correct.

I also add 2 attachments: they are 2 screenshots of before/after visiting artist's profile page
