Have some old issues and got some new ones then i got my Bushido smart.
Pairing: have to choose smart trainer every time (garmin heart & cadens is automaticly choosen).
Connection: looses connection time to time with Bushido or garmin devices (cadems & heart), last ride got all ok but loosed the heart, they don’t seem to like each other.
Stability: Zwift freezes and some time it goes back on line some time it is lost and i got at parial upload, I have MacBoook Pro Retina 2014.
“often” the list of nerby riders goes empty, just the +XX riders is visible, for long times, some time it gets back, some time i get a partial upload.
