I just bought a code 50, downloaded the gateway app and tried to connect it to my galaxy note8. I find that the app connects my note8 to the amp as an audio player (I can play songs in my note8's music library through the amp) but it will not connect the note8 to the amp as an amp controller. In other words, I can play music through my amp but not control the amp's settings. Even though the note8's bluetooth settings shows the amp is paired, the app says it's not connected. I've followed the instructions found in the code 50 users manual as well as the instruction founs in the app itself several times to no avail. Can you help please? Thank you.
