[GA4-Mobile] Mobile traffic critically low — possible mobile crash #6335

@github-actions

Description

@github-actions

⚠️ Mobile traffic below 5% for 5 consecutive days

This may indicate a mobile-specific crash (e.g., React render loop) that prevents
analytics from loading on mobile devices.

Investigate

  1. Open console.kubestellar.io on a mobile device or emulator
  2. Check for React error boundary ("This page encountered an error")
  3. Run mobile Playwright test: npx playwright test e2e/smoke.spec.ts --grep "mobile"
  4. Check nightly react-render-errors report for mobile viewport failures

Context

On March 20, 2026, a render loop in Sidebar.tsx crashed mobile browsers silently.
Mobile traffic dropped from ~20% to <3% for 19 days before detection.
This monitor exists to catch that pattern early.
