After updating to 13.31, multiple users, including myself (Fenix 8 AMOLED), those with Enduro 3, Forerunner 955, and Fenix 8, are experiencing issues connecting their Schwinn iC4 indoor bike as a Bluetooth speed and cadence sensor. While other devices, such as iPhones with Tacx and older Fenix models, still connect successfully, the affected watches are unable to maintain a connection. Interestingly, some users reported that their watch initially connected before losing the pairing permanently. Other Bluetooth devices, like AirPods and heart rate monitors, continue to work without issue. Rolling back to version 12.35 has resolved the problem for at least one user, suggesting a potential regression in the latest firmware update.
