Zwift exagerating output performance

[Pig benis]

Hi folks

I have encountered a problem with my Zwift setup which I haven't been able to resolve, so I'm wondering if anyone else has come across this -

This week my Zwift app which I run on a Win10 laptop is suddenly massively overreading my cadence and speed sensor. I'm using Garmin 2 speed and cadence sensor, and a TacX Bluematic turbo trainer. The issue I'm having is as follows -

I normally will cruise at 200w output, peaking at 300-350w
Now I'm cruising at 700w and if I put any effort in, this jumps to 1400w. I can assure you, I'm not that fit .

So far I've done the following and nothing has helped -

- Rebooted laptop
- Resync'd sensors on the bike
- Resync'd sensors to laptop
- Checked battery health in sensors in Zwift and they are reporting full batteries
- Zwift app is up to date

Has anyone else come across this before? Short of swapping my laptop for a tablet, I'm not sure what else to try.

Thanks all
PB

EDIT - So this is actually a reported bug on the Zwift forums.
