Hi. I have some problems with the player. First, it needs to check the license 3 times per week and its really annoying. The second thing, when i listened Amon Amarth, i tapped on the next buttom, and it started to play Metallica, and the mix is turned off. So what is wrong? I reinstalled the player, and it works properly, except the license error. This week, the player checked the license twice. If you don't trust me, i can send the bill of my google play purchase.
