Avatar keeps moving, but I'm coasting

Seems like the Avatar is pedaling indefinitely at the last power/cadence data transmitted via bluetooth from my powermeter to the companion app. It shows up in the Zwift file as a flat line until I start pedaling again. Not having any issues via ANT+ transmitting from my powermeter to Garmin. Tried restarting Zwift and recalibrating the smarttrainer and powermeter. It’s happened a couple rides now and definitely strange. Any ideas what’s going on, or should I just use ANT+ going forward? Thanks, G

same problem, avatar keeps moving for nearly 500m after I stop pedalling against inclines
