GuffPuff App

Firestore Puff refresh issue         Traced firestore/unavailable error.         Confirmed Android internet permission and Firebase configuration.         Identified forced server-only Firestore reads and incorrect error-message mapping. Android client login issue         Confirmed username login queries Firestore before Firebase Authentication.         Determined the issue was client device/network-specific because production works elsewhere and iOS works.         Documented tests for ISP, VPN, Private DNS, firewall, device time, and cache issues. iOS/Android Browse and People inconsistency         Reviewed six-hour activity eligibility, filters, blocks, incognito mode, self-exclusion, favorites, and proximity sorting.         Confirmed there is no platform-specific discovery logic.         Identified viewer-specific ordering and a Browse comparator defect that can produce inconsistent ordering when                     distance is unavailable.        Established that John123 may be excluded if he is the signed-in Android user or affected by account-specific   filters/blocks.
