Well, I posted pictures, screenshots, sent in loads of requests for support, all to no avail, as the app refuses to run on my Nexus tablet or my Andriod phone.
I had one or two half arsed replies in the early stages, was asked for more screenshots, which I provided, however, seems like they've updated the app to such an extent, that it will no longer run on the Google Nexus (Android 6.0.1) or the Honor 8S android (android 9).
Shame really, without the app, the amp is a pig to use.
Looks like I'll have to let it go and that will be my lesson learned, that is, don't buy something because of the price, the name on the front makes no difference.
It is a perfect example of 'you get what you pay for' and in this case, it was a dogs dinner.

Not really. Out of all the modelling type amps out there, the Code amps are the only ones where the exact same parameters that you can adjust/edit through the app are all editable through the screen and the knobs on the amp itself. So in reality, although it IS more convenient, you really don't need the "app" to make full use of the "amp" and all of it's functions.
