I filed a ticket with this issue and zwift support is now working on it
However I just thought of posting it here as there might be some who encountered the same issue.
This occurred after the software update. My garmin speed and cadence sensor was detected as a Pioneer brand. Zwift picks up the speed and cadence but im not sure if the numbers are accurate.
There is a 2-3 second lag while pedaling. Meaning, when I start pedalling… I can only see my speed on zwift after 2 seconds…
