Watch is reporting astronomically high heart rate measurements after a certain amount of time exercising. Yes I am wearing it correctly, yes I am confident these readings are not correct. This has only started in the last few months. I see others complaining about the same thing. Please fix this Garmin, it is making me regret buying this watch.
Classic example this morning from a zone 2 run:

I was running same pace on a treadmill, but heart rate shoots up to near max and gets stuck there. It's making the watch useless for many of my runs.
