I just bought a Firehawk FX today. Although I read about some issues I was curious. Registered a new account, tried working with the app on my Galaxy 2 Tablet and on my HTC One M8 smartphone. Worked perfectly...
Made a break, wanted to play again and create new sounds.... No login on the app possible! Does anyone know about issues? I tried to change my password, but I always get the hint that my login is invalid. Insane! It works on the Line6 page...why not on the app anymore???
