This is the first software update to watchOS 4 since it became available for all Apple Watch models on September 19. The watchOS 4.0.1 update focuses on fixing a peculiar Wi-Fi issue some Series 3 with LTE models experienced. That issue prevented the devices from connecting to LTE in favor of connecting to an inaccessible but familiar Wi-Fi network.
