1Password App won't install on Apple Watch

For a while now, not sure when it started exactly, I noticed that MFA codes on my watch were incorrect and not in sync with my phone or desktop apps.
On the Watch app on my iPhone 14 Pro, 1Password was listed in the 'Available Apps' at the bottom of the list with a spinning indicator. Pressing that a few times got it come up with uninstall, which although kept spinning and timed out, did uninstall the app from my watch.
Now it won't install. Have restarted both devices, 1Password still listed in 'Available Apps' but install times out.

1Password Version: 8.10.21
Extension Version: Not Provided
OS Version: iOS 17.1.1
