I've just successfully upgraded from 2.2.2 to 2.2.3, and after which Luma no longer displays the menu / sub-categories or the logo on the main page of my website (www.seafordart.com.au), however when you click on a product it does display it correctly ..
Does anybody have any clue?
Did you see some error on your browser console? Or maybe on Magento's logs?
Did you executed this command after the upgrade?
