A lot of people seem completely baffled as to how the pass/rejections could be working on the assessments. A perfectly valid explanation is that it's an overall score with a pass/fail mark. Therefore someone with two above average and one average can beat someone with three above average.
Pretty sure the reports are just the external service anyway, TUI might not even care what your report says. If it is taking a while for your email to come through, I don't think this means your CV is having a manual review, I think the system is automated at this time and the email is just delayed, as happens all the time with email and these systems, particularly when overloaded.
