Apple today seeded the first beta of an upcoming watchOS 3.2.2 update to developers for testing purposes, one day after the launch of watchOS 3.2, a major update that introduced Theater Mode.
watchOS 3.2.2 can be downloaded through the Apple Watch app on the iPhone by going to General --> Software Update. To install the update, the Apple Watch must have 50 percent battery, it must be placed on the charger, and it must be in range of the iPhone.
watchOS betas require an iPhone running iOS 10 to install, and they're only available to developers because there's no way to downgrade the software on an Apple Watch.
It's not yet clear if watchOS 3.2.2 introduces any new features or bug fixes because Apple doesn't typically provide release notes for betas, but we'll update this post should anything new be discovered.
Given that this is a minor 3.x.x update, it's likely to focus primarily on bug fixes.
