My partner wears a Forerunner 745 which was working perfectly fine in the past few weeks. More recently, the watch has stopped tracking heart rate, sleep tracking and no longer displaying a body battery result which I assume is due to the most recent auto-update. When looking at the watch the green sensor doesn't seem to be flashing like it should. Is anyone else having these issues? Is there a possible new update in the works or is there an option to downgrade to the previous firmware? This would allow me to identify if the sensor is faulty or if the firmware did stop the watch from functioning correctly.
