We just got the watch and it’s terrible. Messages from the watch arrive to our phone Garmin apps near instantly whether on wifi or LTE. Messages from our phone apps to the watch can take over an hour to reach the watch, if they ever do (LTE or wifi, it doesn’t matter.). We’ve tested in many locations around our suburban area with strong wifi and LTE capability and it’s always the same. We essentially have no ability to message our son. It only works one way, watch to phone app. We can sometimes get messages to arrive to the watch by swipe closing the garmin app on our phones and reopening. But, this isn’t an actual solution as it doesn’t always work. Very disappointed.
