Hi,
Starting yesterday, anytime I would hit the history button or attempt to connect my Garmin Forerunner 15 to the heart rate monitor, the watch would turn off and the triangle would come on as if it were thinking. It would then erase 2-4,000 steps. I just accidently hit the history button and it erased over 4,000 steps that i've had this morning. So frustrating as I can't access my heart rate monitor for training and it keeps erasing my data and garmin express doesn't stay up to date. I synced the watch earlier when I had 5,000 steps and now it is reverting back to 1620, as if the last couple of hours hasn't happened. I want to go for a run but am finding it frustrating. Please help. How do I make my watch work again???
