No resistance when using Zwift via Bluetooth

[Banks246]

I purchased the Elite Qubo Digital Smart B+. I am using Zwift on my laptop (running Windows 7 -- no bluetooth) and Zwift Companion app on my Android Galaxy 7. It appears that I am successfully connected to Zwift, with Power Source, Cadence and Speed Sensor all successfully paired via Bluetooth. The only issue I seem to have is there is no change in resistance when there is a change in elevation. My MPH will increase/decrease going downhill/uphill but the resistance (or lack of) doesn't change.

Any suggestions?
