I have happily ridden on Zwift for a couple of years - until the last major update and the watts/resistance has gotten all messed up. To register 90 watts on a ride, I have to exert almost twice as much power than I should. I know this was a known problem- but I’m getting frustrated and tired of waiting for a fix.
Hi Glenn
check your weight in the companion app.
Have you double checked your tyre pressure and roller tension? An under inflated tyre or over tightened roller can increase the rolling resistance to your wheel and add resistance while causing noticeable power loss
