After releasing tvOS 12.0.1 to fix bugs, it's time for watchOS to earn your first update after arriving fifth version.
O watchOS 5.0.1 (builds 16R381 and 16R382) was made available today to fix three bugs: one responsible for making some users see an increase in exercise minutes, another that made the reward of standing late not properly accounted for by the watch and a third party which prevented the watch from being reloaded.
Last week, we reported that some Activity app achievements are missing for users who have migrated to iOS 12. Apple itself said it was aware of the issue and promised to fix it in a future update, but it will be for iOS itself.
The update is available on the Watch app on the "My Watch" tab, see General Software Update and follow the instructions provided by Apple.
