I’ve only ridden one ride since updating to 5.50 firmware but during that 2hr ride I suffered a loss of my radar connection, and sometime later a loss of both radar and heart-rate monitor connection. On both occasions the connection was reestablished automatically and within a few seconds. I do hope this was a one-off as I don’t want to return to the sensor issues of the older firmwares again. Has anyone else suffered any 5.50 Bluetooth drop-outs?
