Zwift won't paired in my new vortex

Just bought the smart vortex but wont connect to zwift. I tried all the instructions based on the discussions here still nothing happens. I used my iPhone 6s and have no problem connecting to my phone and tacx utility.

Before opening Zwift make sure that the trainer is not connected to any other app or device including your phone, Bluetooth can only connect to one device or app at a time.

Thank you very much Paul it’s now working …

I have a brand new trainer and a brand new computer.  My computer has found the trainer via Bluetooth, but Zwift is not getting the info.  

Ed,

You cannot pair the trainer to a PC directly using Bluetooth, you would need to use the Zwift Mobile Link on a phone or tablet to bridge the signal or put an ANT+ dongle into your PC. The ZML and the PC would need to be on the same network to bridge the signal.
