Yes to frustration with the test. The mobile version does work and I passed.
My experience with the background check:
I’m licensed in Financial Services, and am required to do a deep background check every year at renewal time in my state, and had a problem with paying again for the same thing just a month later.
I emailed and explained the situation, offering to send them receipts and results in lieu of paying again. The shop fee had almost tripled as they sat unassigned for weeks and there were 6 still languishing at the time I offered to get done in a week, before deadline.
I was summarily declined from being excused from the background check and actually blocked from applying for the shops with no explanation, from an anonymous no-reply email sender.
Makes no sense, and based on other frustrating experiences with the MSC, I decided to add it to my list of blessings.
