Got my son some Wireless Beat Solo 3 for Christmas and while he likes them they are awfully fiddly to connect to his Mini 4 - Press the button, nothing happens, go to Bluetooth in settings and reset bluetooth, wait for it to discover again and then press to connect. I thought this was all seamless with iOS10 and the new W1 chip? I connected it to my iPhone 6s fine i.e. the Solo 3 banner appears on the iPhone when I hold the Beats power button for 1sec. Not sure why it doesn't work on the Mini 4, any ideas?
