I believe it's time to give answers for who brought a amp from Marshall Code series. There's several issues to connect it with the app Gateway. What shall we do? Deliver the amps because we were never informed that there are problem connecting via bluetooth? maybe that's the solution because i can read issues about this since the very beggining...
Thank you for your message, if you are having issues with connection, could you please send some details of the device you are using, also which firmware you have.
