No problems the last 2 weeks. Here is what I do that now works everytime.
I ride with the Inride app for about 10 minutes. I skip the the warmup, pick a random workout, do the the calibration then ride for a few minutes. Then I open Zwift, then I open the app. I make sure the bluetooth icon is searching, however it won’t show Inride since the Inride app is still active on my phone. I then close the Inride app, your bluetooth icon on your phone will flash a few seconds but Zwift should find the Inride power/cadence within a few seconds. If your bluetooth dropped then you have to close Zwift, reopen the Inride app and do over. However, this only happened to me once. This morning I got right on. No probs, no drops during my hour ride.
