I see a similar post on this topic, but it was from 2015, I’m hoping its a fairly common issue
I’ve been with Zwift for about a month, my setup is a Wahoo Kickr and I use the ios app, everything is bluetooth connected (through an ipad). I get an intermittent problem, which seems to happen on maybe 1 out of every 3 rides, where the kickr will just lose all resistance, and basically the game is a bogey . . . it happened tonight 35k into a 40k race, extremely annoying. Sometimes I can get it working by going back into the ‘pair’ screen, but tonight I couldn’t do anything, everything I tried, unplugging the trainer, re-pairing etc, would not work . . (I wanted to at least complete the event, but eventually had to quit).
I’m not smart enough to know what kind of problem this might be … if anyone can advise if it Is a bluetooth problem, or a Wahoo or Zwift problem, or a wifi/network problem? . . . any pointers much appreciated, its extremely frustrating
