Hi,
Lactate Threshold detected a couple of times on Forerunner 965 but it is not updating in Garmin Connect. I notice this issue after I upgrade my watch from FR945 to FR965. I still use the same Garmin HRM-RUN (red one) cest strap.
The last Lactate Threshold I can see in Garmin Connect is missing heart rate value and probably is from older FR945.
My current setup is:
1. FR965 with firmware version 4.19
2. Android 12 on Samsung S10e with One UI version 4.1
3. Welcome for any email enquiries
4. You may access my Garmin Connect account for analysis what's going on
4. Located in Romania
