my code worked ok with my galaxy 5 but i got a new moto z running android 7.1.1 and it will connect to bluetooth but will not connect in gateway. when i push scan for amps it never finds the code amp and yes i pushed the bluetooth buttons on the amp. in the gateway app the in the bottom left corner the amp/phone icon is missing for switching from amp to phone presets. the screen has the blue preset shown but the library has them in yellow. the worst part is that the display on the code amp is not working. it is barely readable. just yellow with the black barely visable. so without being able to program it using the display it doesn't work with my phone either. i have owned a lot of marshalls and still have a bunch but i have never been so dissapointed as i am with this piece of crapp. can't use it live because of the dropouts when switching channels and yea i know about using the same amps and settings in all the presets but that is unaceptable. i have the footswitch and thats a disaster too. one little slip like accidently pushing two buttons at the same time or too fast or twice freezes the amp or reprograms it. yea really cool turning it off and back on in the middle of a song. i tried using it live once and it was a disaster. never again. so i love the tone for recording but now i can't even do that because it wont connect bluetooth and the display is almost dead so i can't program it.
