Text Replacement not working in as many places?

For years I’ve been using the text replacement feature to quickly fill in my email address. But I’ve noticed lately that it isn’t working in many Safari forms. I’ll type my shortcut and nothing happens. I’ll open up Notes and type the same shortcut and up pops my email address, so I know the feature works in some places. So why not Safari?

This article Text Replacement in macOS: How to Use It and Fix If It’s Not Working seems to think yours is not an uncommon problem.

Maybe secure input is interfering?

Thanks, that spotlight trick helps. A few more keystrokes, but better than typing my email address.

It probably is the secure input fields. But why would the email address field be marked secure? It should just be the password field, right?
