the faster i pedal the less power i get

I have just got a trainer today, its the Elite Qubo Smart, the power mag. it’s taken a good few hours to set up and to actually get my guy to move while i cycle. the problem i have now is that as i increase my speed, zwift shows my power and speed decreasing until my guy comes to a stop. Any clues?

Did you find a solution? I have the same problem with the same trainer

If it’snot a smart trainner, check the sensors (speed, cad) , check if the wheel is loose in the trainner. Zwift could be thinking that it has slippery and cut the power.
