Google Ads has introduced a useful diagnostics feature within Channel Performance, found under Insights & Reports.
Advertisers can now review diagnostics across all channels or examine a specific channel to identify:
✅ Missing assets
✅ Assets that were not accepted
✅ Opportunities to improve campaign performance directly from the report
This should make troubleshooting Performance Max campaigns faster and help advertisers take action without jumping between multiple reports.
