This appears to be a backend/internal issue. A separate internal investigation is needed.
The receipt preview in the Classic (OldDot) Scan and Per Diem screens isn't rendered by App code. App only passes the session to OldDot at sign-in (
src/libs/HybridApp.ts:78-127) and when the auth token changes (src/libs/actions/Session/index.ts:104-120). That handoff hasn't changed meaningfully in months, and the bug also reproduces on production.I couldn't verify the cause because the receipt request and its 403 response happen outside this repo. I didn't test on web because this flow exists only in the iOS app. An internal engineer should check:
App-side checks
src/libs/actions/HybridApp/index.ts:103-124).modules/hybrid-app/src/types.ts:1-16). It never builds receipt URLs.Next Steps: Reply with

The matching iOS build is blocked by provisioning, so I haven’t confirmed the root cause. Could an internal engineer help capture the failing Classic receipt request before we select a proposal?
