CYCPLUS ANT+ issue

Hello,

Are there people who use the stick ANT+ Cycplus ?
I have a problem, stick is detected, power, speed, cadence, all is ok but I can’t feel the resistance changed.
Before launch Zwift, I turn off bluetooth and garmin express.

Of course, I tried to pair my Wahoo Kickr core in bluetooth , and all is ok, I can feel the resistance changed in slope.
I think no problem with the stick because it works fine with Tacx software .

For precision, I use an extension cable to improve the connection.

Pair the trainer as power source and controllable using the ANT FE-c profile.

Yes, it’s connected like that
“Wahoo FE-C …” (Contrllable, power source, cadence)

And you are 100% sure the trainer is not connected via Bluetooth or ant+ to any other device or application?

Yes, sure. I just use my computer with bluetooth turned off.
I will ask at the support.

Thanks,
