Ever since the new Apple Watch Series 3 was released, some owners and reviewers have mentioned that the model with built in LTE tends to have issues with lingering on known WiFi networks and being able to switch between LTE and WiFi. Sometimes it will connect to ones which have captive portals, which are unusable on the Apple Watch.

Users who’ve been affected by this can download watchOS 4.0.1 now, via the Watch app on iPhone.
