After getting the new IPhone 16 pro i updated the software to my Iwatch series 9, and the Bluetooth connection is not working. I took it to Apple Store and iI was told to wait for the next software update, but at this point as my IWatch is not connected to my phone not sure how I am going to get a notification that there is new software to update. They were even not able to get a diagnosis of the watch as it was not connecting.
