Calibration iOS iphone failing

I’m trying to calibrate my Tacx Neo, if fails every single time, already updated the trainer firmware, updated the app, it just fails when the spindown hits 3kmh, tried it 20 times. Is this necesary to train properly?

To the best of my understanding, the Neo does not need any calibration.

In fact, that is often stated as one of it’s best features when compared to other trainers.

There is no calibration or spindown of the Neo.

Power up your Neo.
Start TR.
Pair the Neo.
Begin suffering!

No need to calibrate. Get on and ride on. 2 years and still riding 3-5 times a week

Thats what i wanted to hear, thanks guys
