Smartwatch firm Garmin is facing a backlash after customers around the world complained their devices were not working.
Some users reported seeing a blue triangle when they tried to turn on their watch, while others were stuck on its start-up screen.
Garmin’s Fenix 8 smartwatches, which retail for just under £1,000 ($1,200), are some of the devices to have issues – however not all watches are affected by the outage.
The firm told the BBC it was aware of the problem, and suggested users reset their devices – adding it would “provide more information on a permanent fix when available”.
Customers have taken to social media to express their frustration at their smartwatches not working properly and what many see as the company’s slow response.
