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.
