I've set up a pace alert with a target range of 5:00-5:15 per kilometer. However, I've noticed that when my pace goes 5-10 seconds outside this range, the alert takes several minutes to trigger, even though the display shows that I'm running at, for example, 4:50 or 5:20. The alert doesn't go off in time to warn me.
On the other hand, when I set heart rate intervals, the alert works immediately as soon as I go out of range.
However, I’ve also been experiencing an issue with heart rate measurements. Sometimes the heart rate reading "freezes," even after changes in activity, like running uphill or resting. While this isn't a major issue, it does occur occasionally.
What can I do to fix these problems? Any suggestions or solutions would be greatly appreciated!
