Resistant on tacx flux

Recently I bought a tacx flux trainer. I paired it with my laptop and my iPhone via ble connection. I started use the free trial zwift version but there is no resistant in any ride either there is uphill or downhill. I don’t know if I did something wrong so I wonder if there is someone who can help me.

 

Make sure it is paired as a controllable trainer.

Thank you but i 've allready check it.
