I've been using Musiccast with a 3050 for years and recently bought an A8A and again it worked fine. But in the last few days the app can't see my amp when I start Musiccast, on 2 different devices, and it will only work after a full setup again. It works fine but a few hours later both devices fail to see my amp connection again!!! Clearly there's z defect here but is it the app or the amp firmware? Either way: UNUSABLE!!! (Error: Previously connected device is not found (Code-201))
