i have fenix 6 pro solar and same problem with hrm pro plus... its new and used it today... connected to the watch, add devices in the connect app, still the running dynamics arent showing anything other than the basic candence and stride length... while verified with collegue data, i could see the device and sensor in the overview tab and stat has all the running dynamics. for me, only the device alone shown against the activity... not the sensor details. when i enable, it is syncing the hrm, device etc but not actually connect with the app is my thought
