Can't find power source on iPhone or iPad

Hi, I just bought a taxc neo and I can’t find the power source on swift when trying to pair? I’m using a iPad Air 2, I’ve also tried it on my iPhone? 

Its just searches. 

I’ve updated the neo and have also downloaded mobile link, tacx utility and tacx training just in case these are the issues? 

Any help would be fantastic 

many thanks 

Tim: Bluetooth devices pair exclusively, one to one. If you have anything paired to the Neo, Zwift will not be able to pair to it. So make sure that nothing on your iPhone, iPad or anything else is paired to the Neo.
