It's not the first time... I tweak some random setting in the watch - this time - Auto Detection of Max HR. And behold!! The watch now makes high pitch beeps (into my earbuds) each time it reports something.
Previously I've had switched some unrelated setting and workout suggestions began to show up on my watch, although is never happened before even if I had workout suggestions turned on.
How?? People? How it's even possible to write a software in such way?
