I wear my Forerunner 945 everytime except for a few minutes when I take a shower or when I charge it. I suddenly didn't have a heart rate record between July 9, 12 midnight and July 10, 6PM. I don't know why it happened.
- I wear my watch the same way. If it became lose, why only now and why at exactly 12 midnight did it stop recording heart rate?
- My watch face is recording my heart rate and I'm 100% sure that the watch is measure my heart rate but it somehow doesn't save it when I sync it.
- I tried syncing my watch to my phone, connecting my watch to my laptop and syncing with garmin express, my watch has the latest software.
PS: the customer support I contacted is clueless. He didn't give a definitive reason and asked me to do a factory reset and lose all my data. It feels like a sledgehammer solution to an otherwise simple problem.
