I have owned a Garmin Venu 2 since two years ago. Since the last summer, I have problem with the HRM that seems not working properly. I have to restart my watch to get the HRM back in order again. However , after a couple of hours, the sensor stops again both in activity mode or not. I was looking in your forum for similar issues finding a thread that is already closed. My UI version is 17.04 for the moment. Please let me know how this is possible to be resolved.
