Permission prompts that quietly break funnels
A cliff in the chart is sometimes an event that never fired after a dialog.
When a conversion path drops forty percent between adjacent steps, product rewrites often start before anyone watches the live stream. On Android, a notification or location prompt can swallow the next client event entirely.
Walk the path on the devices your users hold. Note client-only fires versus server-confirmed steps. Identity resets between web and app invent abandoners who simply continued elsewhere.
Conversion Path Verification stays deliberately narrow: one path, deep QA, a script you can rerun after every release.
