• Reframed DA0-001 throughout the app as a retired legacy reference and added clear notices that it is not current Data+ exam preparation. • Clarified timed practice and PBQ-style activities as independent knowledge review, not official exam content or a certification-readiness predictor. • Improved purchase, restore, and entitlement-state handling. • Improved progress persistence, study planning, and flashcard review behavior. • Corrected content and fixed reliability issues across core study screens.
