I don't know when it started because I have not been using "Free" training much before. I typically use it when traveling. And sometimes at home when I don't have time for a full planned training. Anyway, in "Free" training, my Fenix 6X Pro appears to be guessing when a set ends (and begins). And it get's it completely wrong. So while I'm in the middle of a set, the watch beeps and ends a set. Sometimes it starts another set, if I continue doing reps. Sometimes it doesn't. Sometimes it starts a rep while I'm resting. "Free" training is completely useless for tracking a workout because the recorded sets is more noise than matching what I did.
I looked for a setting that controls this artificial non-intelligence, but no luck. What's going on here?
