Can't update watchOS
I have a Series 2 watch. The Watch app on my phone indicates I have a watchOS update (I'm still running 4.0 so I know I do) but when I tap Software Update it says "To update the software on your Apple Watch, you first need to update the software on your iPhone." Problem is I'm already running iOS 11.2.6 so there is no update. I've tried restarting the phone and the watch to no avail.
