bought one yesterday from argos uk,when I connect to the app I get "cant find controller",the led on front is flashing a amber colour,thought it might not be charged so I plugged into usb charger then opened controller and light went to blue,left it plugged in and connected to the app and it worked straight away,updated firmware on both ,the controllers shows 100% charged,as soon as I unplug from charger it looses connection,amber flashing light again and says cant find controller.think ill just take it back today for refund
