Today Apple released watchOS 5.3.2 for the Apple Watch Series 4. The update is meant for users of the Apple Watch Series 4 using devices like the iPhone 6 that don't support iOS 13, which means they subsequently can't update to watchOS 6.

There is a small number of users, but apparently it's big enough to warrant attention because Apple released a special update for them. The affected iPhone models include the iPhone 6 and iPhone 5S.

This decision is not a problem in a vacuum, but with users on devices like the iPhone 6 using a newer Apple Watch Series 4, this presented a conundrum.
