Since the latest beta tests and now stable, on runs my heart rate drops out. It's really frustrating as my training is heart rate based so it's really throwing me off.
I've contacted Garmin via the email request form three times and had zero reply. Don't know why. But in the run all of a sudden my Garmin will say my heart rate is below target and I think hmm that's odd. It will continue going down. Then suddenly back up. Afterwards it will show it dropping to 0 suddenly then back up. First time this happened once, now it's happened two or three or four times ever since.
I've also had it where Pace Pro doesn't say how far or behind I am. Had that half dozen times, ever since getting the 265 in March. No reply from Garmin again.
I've restarted, made sure polar H10 is up to date. Previously had zero issues for 4/5 months.
