Others have posted this here, but I'm posting it again in hopes of getting the attention of the Garmin team.
This is my first Garmin, so I don't know if it's standard for their products, but the syncing to my iPhone is really shoddy. Sometimes I turn the watch on, and it syncs perfectly. Sometimes it doesn't, so I toggle the watch off/on, and it works. Other times I have to force quit the Connect app. Sometimes I even have to turn my phone off.
I've had no problems with the watch once it syncs. In fact I've really enjoyed using it. This syncing issue feels like a problem from 15 years ago, though, and not something I'd expect from one of the top device makers.
Really hoping this can be fixed.
