I have been unable to use BLE to connect the Kickr Bike since the update in January 2021 when steering was introduced specifically for the Kickr bike. My internet connection is solid, the Kickr Bike has no issues connecting to other apps (Fulgaz, Kinomap, Wahoo, RGT, etc.) and Zwiftalyzer shows no issue on the log files. I get an intermittent but consistent Error 3 on the bike, showing in the gear display after 20 to 45 minutes of riding. Then the bike disconnects with Zwift and will not re-pair on the pairing screen. It requires a hard reset of the computer (Mac) and bike. Zwift says it is the bike, Wahoo says it is Zwift and no resolution after many email exchanges with both companies. I almost returned the bike for this problem, but gave up on steering and went to ANT+ only. 8000 km later and ANT+ causes no issues so I suggest switching to ANT+ and disabling BLE on the computer.
