same here. After updating to iOS 16 and WatchOS 9, there were no Apple Watch Mirror. Wonder if the feature is limited to specific Apple Watch models only? https://appleinsider.com/articles/22/07/11/hands-on-how-to-mirror-your-apple-watch-to-iphone-in-ios-16

I do have the same case. and apple service center recommendation is to replace the screen and billed under customer. I think Apple should look on to this, it might be a hardware bug
