Garmin’s instructions seem to suggest that devices will need to be factory reset if a power cycle does not work. Reconfiguring a watch from scratch would be inconvenient, so it might be worth waiting to see if Garmin can issue an update that resolves the issue. If you cannot wait too long, you might just have to go through the hassle.

Garmin users are reporting that their watches crash when using apps that require GPS access and then get stuck in a reboot loop, showing a blue triangle logo.

Some Garmin users have reported issues with a blue triangle appearing on their device and it getting stuck in a reboot loop.

Earlier this week, an unexpected bug bricked many Garmin watches, leading to many of the company's wearables being stuck on the startup screen or showing a blue triangle of death while loading a GPS activity.
