Apple today released the fourth beta build of watchOS 4.2.2 for trying out on the Apple Watch before a release to the public sometime in the future. This comes after the third beta was released last week.
To install the beta, navigate to the Watch app on your paired iPhone and tap the “My Watch” tab. From there, go to General > Software Update and you should see the build ready for download. Be sure to place your iPhone on Wi-Fi while downloading this software as it’ll surely gobble up plenty of your data.
We have yet to notice any user-facing changes in the latest watchOS beta build, but we do know there are some bugs that have been squashed. We’ll update you if we find something worth noting.
