The Google Ads Ad Preview and Diagnosis tool is currently experiencing a significant issue, displaying an unremovable CAPTCHA box. This prevents advertisers from using the tool to preview their ads in Google Search results.

The Ad Preview and Diagnosis tool typically allows users to understand why their ads might not appear as intended. According to user reports, the CAPTCHA problem has persisted for over a week, with one user noting attempts on multiple devices and internet connections without success. No timeline for resolution has been provided.
