Even better than that, while some of them can sync over wifi directly, most of them sync over Bluetooth, to your app which must be logged in, which does nothing except use the phone’s internet connection to upload the data to garmin, and then the app needs to re-download all the data from garmin’s server before it can be displayed in the app.

So they can sync over Bluetooth… but in a format that garmin’s app can’t use or understand so you must be connected to the internet to actually see the data.

For a device which generally should work with bad/no internet, it’s completely insane.
