What’s going on with WordPress????
Nothing, I’m afraid.
But I’m curious what’s going on on your site.
Please provide a screenshot of your editor screen so we can better understand what you’re dealing with. (Upload your screenshot(s) here https://snipboard.io/ and add the URL in your response.)
For what it’s worth, I just installed a fresh copy of WordPress just to test this (version 6.5.3, default theme, no plugin) and I can click on the highlighted elements below to change the publishing date/time and permalink respectively… and both features are fully functional.
Standing by to help!
