I have a hrm-pro and fenix 5s. When I start a workout it recognizes de HRM-PRO, also during breaks I see the HR being transmitted, but when i am done swimming and end the workout out of the water, it doesn't sync the hr data from the hrm-pro to the watch. When i review on the app it recognizes i had the hrm but there is no data for the hr, how can i solve this?
