Looks like Garmin encourages robbery of Garmin watches. Just happened to me and my wife. A Fenix 7 and a Venu 2S
We have the Serial Numbers and proof of purchase. Still, Garmin refuses to block or try to track the watches.
The devices are added to your accounts, but Garmin let ppl freely use and add devices to other accounts without being removed from original accounts first.
They say they will only provide information to the police. But the police is slow and burocratic, might take a very long time for the police to contact them, or it might just never happen, considering Garmin has no official address in Brazil.
What about the rightful owners? After charging so much for their watches, they should take better care of their customers if they wish to keep them.
