watchOS 4 install failing

[netdog]

I get all the way to "Verifying App" and then it suddenly says "Install Failed - Open App" even if the app is open. App is otherwise successfully communicating with watch.

Watch Series 0
iPhone 6S with 11 installed today.

Did you try reboot both Watch and iphone?

That seems to have done it.
