Can't connect new Neo bike to Zwift (only Tacx utility)

Just received my new Neo smart bike today :O)

Connected to Tacx utility and updated firmware to latest, then tried to jump on Zwift but could not detect bike on any device - Chromebook, android phone or Apple TV.

Turned everything off and tried Zwift without opening tacx utility in case this holds the Bluetooth connection, but still no joy.

Sure I must be doing something silly if bike connects to Tacx utility, suggesting Bluetooth is working?

Previous user of Neo 2T trainer and no similar issues with this.

Help / advice appreciated

Many thanks, Craig.
