Running dynamics does not show while I'm running even though my HRM Pro is connected to my watch. The firmware is up to date. I made sure the HRM Pro is connected through ANT+. The running dynamics data fields are shown on the settings when I access the data screen settings but when I go back to the run, the data fields are not there. I changed the battery and it did not help. The last time running dynamics was captured was on a 2.5-hour long run, after that, I flew out to a different country. When I used it in the new country (France) it stopped recording run dynamics.
