Preflight reads the existing choices and checks for answer-based page navigation.
Routing safety
Google Forms section routing can break when choices are replaced
“Go to section based on answer” belongs to the existing answer choices. A bulk refresh can rebuild those choices without their destinations. The safe default is to detect routing and refuse the update.
Watch the routing blocker work
This controlled 31-second proof shows the destructive-risk condition being detected before any choice write. It does not claim to preserve routing.

The failure mechanism
- A dropdown or multiple-choice question has answer-specific section destinations.
- An add-on reads new labels from Google Sheets.
- The update replaces the old choice objects with a new set of plain values.
- The labels look correct, but their original section destinations are gone.
- Respondents continue through the wrong path even though the update appeared successful.
Google documents answer-based routing for dropdown and multiple-choice questions, and Apps Script exposes each choice's navigation type. That makes the risk detectable before a write.
How FormSuite Choice Sync handles it
Block, do not guess
A routed question is disabled in the mapping selector and rejected again in the core write path.
Protect every update path
The same guard applies to sidebar updates, menu updates, and automatic triggers.
Protect quiz scoring too
Questions with a correct-answer key are also blocked because choice replacement can erase scoring.
Safe alternatives
- Keep the routed question static and sync a separate non-routed question.
- Remove routing only if the workflow owner confirms it is no longer needed.
- Use custom Apps Script when you must recreate every label and destination together—and assign someone to maintain it.
- Always test on a copied form and verify every branch in the public respondent preview.
Important boundary
This protection does not turn Google Forms into a live dependent-dropdown system. If question B must change immediately after a respondent answers question A, use a form platform or custom application that supports respondent-time dependent fields.
