I cannot play songs whenever I am connected to the internet, I have huge delays when I click on a song (2s to just not playing at all), even if I the songs/albuns downloaded. It takes a long time to load my albuns, even the ones I have downloaded as well. 

When I am in offline mode, it behaves normally, everything loads instantly, so I have been using it all the time.

I need a solution for the issue when I am connected to the internet

Hve tried reinstalling, logging out, clean reset and even messing with the offline devices, nono have worked.
