I found this update to be very frustrating. Was there any A/B testing? Was there considerations to make a soft launch (e.g. an option to opt out)?

Why are you asking after the fact? This section of your platform is one of the most critical sections for us to improve our understanding of the exam. This appears careless/thoughtless, especially for the amount we pay monthly.

I am now also receiving Internal Server Error's when selecting different drills. Please consider that some of us have limited time/resources and put our trust in your product/platform.

From A Concerned Stressed Test Taker, thank you.
