Updating affected Ultra watches to the latest post-release version of watchOS 9 doesn't fix the issue, which Apple is apparently aware of. The Noise app cannot check sound levels when Apple Watch is in Water Lock or while the microphone or speaker is in use.īased on reports, the issue can be temporarily resolved by restarting the Apple Watch until the bug eventually manifests itself again, suggesting the problem is software-related rather than a hardware defect. Users have taken to the MacRumors forums and the Apple Support Community forums to relate the issue, which results in the following error notification from the Noise app, and also prevents system functions including Siri, Dictation, and Handwashing detection from working: Photo shared by MacRumors forum member 2259 depicting the issue
