Take the guesswork out of targeting with updated Diagnostics

💡 What is Diagnostics?
Diagnostics helps you quickly check if a specific user qualifies for an experience (or why they don’t)—without guessing or digging.
⭐️ What’s new
The new Diagnostics page now shows pass/fail results for each targeting condition and explains why—including the actual user property values that caused a mismatch. You can:
Open it from any modern conditions editor, the User Profile’s Eligibility tab, or a Segment view.
Use the built-in AI explainer for a clear, concise breakdown.
See audience size with the new calculator right on the page.
🚀 Ready to get started?
