Sweat loss and Hydration tracking - Instinct 2X

Hi all,

I just got my Instinct 2x this week! so far very pleased with it. Very hard to kill the battery Sweat smile

I was wondering why there's no estimated sweat loss integrated after activities? I added the hydration tracking widget (which is very laggy btw) and set it to auto increase, but it doesn't show any estimated sweat loss data and so the hydration goal stays at the same set level (even if I change it in Garmin connect).

Am I missing something, or does the instinct 2x lack  this quite simple feature? My Garmin vivomove has it...
