I have a new Venu 2 plus, on the latest firmware and have frequently encountered frustrating problems with syncing hydration information between watch and Garmin Connect.
This function very frequently is out of sync, sometimes even out of sync on the actual watch itself, you add 2 cups of water, back out of the widget and watch the widget summary display delay on update, or not update. Then IF it does update on the watch, the phone will not update correctly even if a forced refresh is used.
This seems to have been a long term problem for something simple. Is there a fix in plan?
