Latest firmware update totally crashed my watch. It now just flashes the blue triangle every few seconds. Can’t connect via Bluetooth bnor garmin express. Can’t reset via buttons, Already had major issues with display which only works once every two weeks for a few minutes which is what I was hoping this firmware update would resolve, bought the watch in bali live in Zanzibar, local Tanzanian agent won’t exchange it. What do I do, where do I send it for exchange. Lasted only two months before issues arose. Been with garmin for 10 years on many devices, this is my first faulty one
