Ensured proper sorting, history tracking, and month-wise data refresh across modules.
Major Bug Categories Identified:
Incorrect claim approval logic and inconsistent status updates.
UI/UX issues such as incorrect fonts, repeated year display, missing back navigation, and unreadable receipts.
Performance issues: app crashes, camera failures, slow image updates, and incomplete submissions.
