**2. Added: Update** (identified) · 2026-11-13 17:34 UTC

```diff
+ We've identified the cause of the slowness. A slowdown in Google Analytics 4 (GA4), which CMP uses for analytics data, delayed the analytics settings that load with CMP. This slowed the homepage and caused timeouts. Only organizations with Google Analytics 4 connected to CMP were affected. Organizations without GA4 connected saw no impact. A fix to limit the impact of GA4 delays has been merged, and we're finishing its rollout and monitoring. We'll post another update once things are back to normal.
