Apple today released the third beta build of watchOS 4.2.2 for testing on the Apple Watch before a release to the public in the future. This comes more than two weeks after the second beta was released.
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.
