- Quiz Initializing Failures: Fixed a core frontend processing loop that intermittently blocked enrolled learners from starting or launching designated course quizzes.
- Mobile Quiz Interaction: Restored a structural layout asset by adding the missing Quiz Details interface trigger for touchscreens and mobile responsive layouts.
- Zero-Value Coupon Exception: Corrected a fatal mathematical calculation oversight that threw unexpected PHP exceptions whenever a 100% checkout discount coupon was applied.
