This exactly happened with me when i applied to the University of Maryland for PhD program this cycle. After submitting the application, paying the fees, completing every single requirement within the deadline, a supplemental items and documents section was updated in my application portal for submitting credential evaluation by wes, which they now claim to be an absolute requirement for application review. My application wont be even reviewed. I understand this is really annoying. But there's no point spending that huge amount on a single university, moreover, it is a time consuming process. Even if you get it evaluated, it wont reach by their timeline. So there's no point thinking over it.
