Hi, i also have the same issue than Karballo. The pause button, don't change to play and reverse. I also use version 2.0 (final) not the alpha. Zuk z2 Pro with AEX 5.7 I think on the alpha version that it work, but i have to confirm. After a reboot i have also to start the service, because it crashes. Very good app. Many thanks. Edit: i confirm that this 2 issues only occur with the play store version 2 final. With the alpha version all works as expected.
