There is a 99.9% chance that the trick download is the final report. We are able to download it because IQAS has already uploaded our results but are yet to change our profile to download it.
The trick we use works by changing the address of our report to the address IQAS puts in the "download report" link. That's how we came to know about the trick, by looking at various profiles and how the web addresses changed for each status. Final review and Complete status have the same address, and is very similar to download report status' one. After the change of date of final review, or when complete showed for a while, we were able to download the report. Have been testing the trick here with numerous profiles, and able to download almost always.
In about 200-250 reports downloaded with the trick, only once was a final report different from the one downloaded with the trick. It had a correction of name or date or birth, I don't remember which. The credential outcome has never changed.
