Happend lately - after swimming activity didn't worked for 2 days, after restart - worked again. And yesterday - after long walk, when MoveIQ detected it, it also stopped recording and measuring any stress... even manually says that pulse is weak and it's not possible to measure it:-( After restart working well...

New firmware and not additional apps/fields etc...

Hello! Can I have you go to the activity tracking menu and turn it "Off". (Menu>Activity Tracking>Off) Once you have done that, then let's do a hard reset on the device. (Press and hold the power button on your watch.  Ignore the "Power Off" question on your watch, just continue holding the power button pressed down until the screen goes blank.  Once this occurs, you may release the button.  Allow the watch to sit powered off for a full minute, then you may power it back on by pressing and releasing the power button.) After this, please turn back on the activity tracking and let me know if the issue remains.
