Hi, my epix2 v 7.2 is not using the hrm tri, it shows connected and the ant version, battery level, but it will not be used on trail run, never tried another activtiy with the hrm belt. Disconnecing and repairing does not help, also after starting the activity the green leds from the watch are still on, looking in the settings while activity is started, under sensor it shows connected but will not be used. No balance, ground contact time will be recorded, on my fenix 5 never had an issue.
