Apple pushed the watchOS 9.0.1 update (internal version number: 20R8380) to Apple Watch users, 10 days after the last release.
watchOS 9.0.1 is available for the Apple Watch Ultra, and for the first users who receive the “Apple Watch Ultra,” this update will be available as soon as they get their hands on it.
According to Apple’s release notes, this update addresses issues that can cause audio distortion during calls when using the speaker.
It should be noted that due to the caching problem of Apple’s regional node server configuration, there may be a slight delay in detecting the update in some places, generally within half an hour, not too long
Apple Watch Ultra users can download the update by opening the Apple Watch app on their iPhone and going to General > Software Update. To install the new software, the Apple Watch needs to have at least a 50 percent battery charge, be on a charger, and be in the range of the iPhone.
