I'm having all of the above issues. The flashing lights, the solid lights. The reason I was told to try an update in the first place was the app wasn't even allowing to change tones either in search or in the presets. Now, nothing is working at all. It seems like from what I'm reading and the reviews, it's simply a device for troubleshooting and not actually using to jam. I forgot I bought it as an amp, really frustrating.
