Apple has begun rolling out the third beta build of watchOS 5.3 for testing on the Apple Watch. This comes two weeks after the second build was seeded. Only developers have access to this software, so everyone else will have to sit tight and wait for the public release in the future.
The new software can be installed by going to the Apple Watch app on your iPhone and searching for a new software update. You’ll have to have your Apple Watch connected to its charger in order for the update to install.
With this update, it’s expected that Apple will include bug fixes and security improvements. Of course, if any user-facing changes/features are spotted in watchOS 5.3, we’ll let you know.
