# PDIAP-15765 - AO DOB field error not showing investigation

## Status

- Active again
- Move back to In Progress on the next workday
- Small XFlowSDK compatibility PR opened for the iOS-side fix

---

## Context

- This ticket is tied to an AO DOB validation issue.
- The issue was confirmed for authenticated users in the `HybridYouthAccountOpening` flow on the `TeenIdentityCheck` page.

---

## Confirmed Findings

- The issue reproduces only for authenticated users based on the currently stored evidence.
- Root cause was documented.
- The original external report was incomplete.
- For the config discussion, `CheckIdentity` was already correct. The `TeenIdentityCheck` issue had two config gaps inside `validation-rules`: the root key should be `validations`, and the age gate also needs `eighteenOrAbove` there when that rule is required.
- Follow-up validation on April 13 showed two distinct authenticated scenarios rather than one uniform cross-platform issue.
- A `HybridBrokerageAccountOpening` / `JointIdentityCheck` scenario reproduces on both iOS and Android.
- A `HybridYouthAccountOpening` / `TeenIdentityCheck` scenario works on Android but fails on iOS.
- Current evidence suggests Android is more flexible in how it decodes rule variations, while iOS is stricter about the expected `validation-rules` structure.
- Later validation on April 15 showed the original `HybridYouthAccountOpening` / `TeenIdentityCheck` issue no longer reproduces once the payload uses `validations` instead of `birthDate`.
- A minimal XFlowSDK fix was still prepared on April 15 so the iOS `.apxDateSelect` path also falls back to `birthDate` for a future release.

---

## Current Guidance

- Treat the iOS-only `HybridYouthAccountOpening` / `TeenIdentityCheck` discrepancy as the main client-side issue currently aligned with the story.
- Keep the cross-platform `HybridBrokerageAccountOpening` / `JointIdentityCheck` scenario separate until it is clear whether it is a service/config issue, a distinct bug, or an unreported rule-processing difference.
- Keep the authenticated-user qualifier whenever this ticket is mentioned.
- Do not describe it as a generic validation issue without the `TeenIdentityCheck` and auth context.
- The originally reported Youth issue appears fixed immediately by the service-side payload update, but the XFlowSDK fallback PR should still be released so iOS handles the older `birthDate` format more safely.
- The `HybridBrokerageAccountOpening` / `JointIdentityCheck` issue is different from the original Youth report: the rule content itself does not include `ageRange` or `eighteenOrAbove`, so that path still points to a service-side update rather than the same iOS parsing gap.

---

## Next Step

- Get the small XFlowSDK compatibility PR reviewed and released.
- Close the story with comments explaining that the immediate Youth issue was resolved on the service side and that the XFlowSDK fallback fix will be available in the next release.
- Keep the separate `HybridBrokerageAccountOpening` / `JointIdentityCheck` scenario out of the client-fix scope unless later evidence proves it is part of the same issue.
- Consider a separate follow-up ticket for the cross-platform service-side issue if that path still stands after consumer confirmation.
