Smart Flux 2 does not simulate

Hi,

I have a problem with my new Smart Trainer Flux 2:
when I pedal my trainer does not simulate any slope.
if I set a workout it is not configured correctly or does not increase or decrease its intensity. I activated ERG MODE but to no avail. the connection is managed via ANT+ Tacx with MacBookPro 2018.

I calibrated the trainer using the Garmin TACX App and updated the software v5.5
help me!!
