Correct answer & explanation
✓
Examine the UI Macro record for syntax errors in the HTML or Jelly script.
The first troubleshooting step is to examine the UI Macro record for syntax errors in the HTML or Jelly script (Option D). Syntax errors are the most common cause of a macro not rendering. Checking the browser's HTML source (A) is possible but not the first step. Ensuring the UI Macro is in global scope (B) is less likely the issue, as macros are typically accessible within the theme. Verifying UI Scripts (C) is unrelated because UI Scripts are separate client-side resources, not the macro's own code.
