That irregular heart rhythm notification is a great feature, and I love that they are updating it. It was very helpful to me. Love any health related updates.

PSA: This is the first Watch OS update that requires newer than iOS 15.1.1. :)
My mom just tried to update her watch and it told her that she had to update her phone first (both watch and phone are on the latest, not today’s, last revision. )

nice quality of life improvement: inputting your passcode immediately unlocks the watch instead of having to tap OK to submit it.

My iPad Pro, iPhone13 Pro, MacBook Pro, and both my Apple Watches (7 & 6) updated in a grand total of 20 minutes. This was a very smooth update.

It’s taking 2 hours to download …..is it normal??????
Any chance it's trying to download over a different connection (either cellular or WiFi, vs. using bluetooth from the iPhone)?

I just updated my watch (Series 5) and it took less than 5 minutes for the whole process.
