I have been riding on Zwift for 18 months, having ridden around 4K kms and never had any kind of power dropout.
After the latest update 8/01/18 I experienced two in just one ride (my trainer lost connection)
I’ve been having the same trouble. I use the mobile link to connect my desktop with my CycleOps trainer. I dropped out three times during Stage 2 of the Tour de Zwift.
Running Zwift on iPad Pro. Rode London for about 45 minutes today and experienced power dropouts for a couple of minutes before things went back normal. Running first gen KICKR.
I’m experiencing the same problem, Rode in a 50 minute group workout this afternoon, and at least 10 times, the power would drop to zero, and come back up within a few seconds. I have never experienced this previously on Zwift.
