I’m new to Zwift. Before I post this I did some research in google and this forum. I didn’t find this issue common.
I am using MacBook and I paired both Wahoo speed / Cadence sensors. It picked up both sensors quickly. No issue with Cadence readings.
Speed sensor readings are very accurate when I roll the wheel in Device Pairing mode. As soon as I start the ride. Speed drops significantly. I bought an Ant+ dongle because I heard people saying older MacBooks don’t have Bluetooth 4 to connect with Wahoo speed sensor. So I basically disabled MacBook Bluetooth to make sure it’s picking only Ant+ but I’m sure this is not connectivity issue. Because pairing screen of Zwift shows correct speed and the Ride screen messes up.
I even changed my trainer type. Basically I use a bike roller. But that didn’t help either.
If you have another suggestion for virtual bike training other than Zwift, please comment. This has been frustrating for me so I’m ready to switch to another app.
