The recent bug fix update resulted in a strongly negative impact, with the average iOS rating declining by 0.36 stars to a post-update average of 1.67. This decline is driven by critical billing issues where users report subscription cancellation failures and subsequent unwanted recurring charges. Additionally, some users allege that outdated practice questions are causing them to fail their written exams, further weakening post-update momentum.

Performance enhancements and necessary bug fixes to keep things running perfectly.
