I'm having an issue saving a page properties in 6.3 using touch ui. I navigated to the page using site.html and clicked properties. I changed the property and clicked Save & Close, but nothing happens. I can edit the property using crx, but touch ui does not work.
There are no log messages either (perhaps I need to turn up logging but which package?).
Okay so what was going on is that a required page property was not filled out. The thing that was confusing is that the required field was on another tab, so I couldn't actually see it. There should be a banner/snackbar/something so that it is easier to see even when on other tabs.
