I have the Tacx Flow and ZML pairs perfectly with the trainer, my computer recognises that the ZML is paired but continuously searches for devices and the Tacx Flow never appears.
Been like this for a while now, SO frustrated and considering cancelling my Zwift subscription!
You might try removing all pairings between your Tacx and phone. On Android, anyways, having the phone paired with the trainer will cause the computer to not see the trainer. Not intuitive, that one.
Thanks for your response. Nothing else is paired with the trainer. It worked fine last night and now nada, I am contacting Tacx too. At the end of my tether with it and will probably cancel my subscription as it’s wasted.
