Seems to be working via Android Tacx app (cadence is shown in there).
Can’t see the cadence thought on my Zwift (tried on laptop and PC with 2 different Garmin Ant+ dongles).
It is new Neo 2, had Neo before and I think it worked fine.
Does it mean that I’ve got faulty item ???
Unfortunately got a faulty item 
The Tacx app was reading my Garmin cadence sensor and not Neo 
(hard to know the serial number of every ant device ;))
Tacx confirmed faulty cadence sensor. Don’t think it is Tacx fault as it was delivered by a Yodel.
Security foil around the box was ripped all around and box had a mark from a drop.
Neo 2 seemed to be well packed, but drop from a van it is not something that many devices will survive.
Force your shop not to use Yodel !
Now I have to wait ~ 7 days for a replacement.
