No resistance when using Zwift via Bluetooth

[Banks246]

I just purchased the Qubo Digital Smart B+. I am set up as follows:

* - Windows Laptop without Bluetooth;
* - Zwift Companion running in my Galaxy S7.

I can connect to Zwift. I am connected via Power Source, Controllable and Cadence.

Everything seems to work fine except there is no change in resistance regardless of the incline/decline. I have adjusted the resistance setting but there is no change.

Thoughts?
