I noticed a small bug today (or at least it seemed so). I paused during a ride to refill a water bottle and stretch (5 mins?). When re-starting, zwift would no longer display HR data.
I paused again, went back to check my devices and my HR was there and showing. I tried unpairing and pairing again, it was displaying fine on ‘pairing’ screen, but again nothing when started riding again. Kept going anyway as didn’t want to exit out and start all over again.
My HR continued to record on my garmin with no issues.
Not sure if this has been seen before, but wanted to report it.
