This is what the requester wrote. Does anyone of a suggestion on where they are going wrong? For the sake of transparency here is what I did: to avoid issues similar to the one you had I have cancelled the batch I have then followed the script, reverting “rejected” to “approved” on the CSV file since there is no tab to input an “X” but rather the word in itself It did not seem to work, probably since I also had to delete the justification of the rejection from the tab, which is what I the did. One re-uploading the file I get the a error "Your file could not be process, error on line 1"
For anyone who has a similar issue, here is the solution the requester finally found that worked. https://www.reddit.com/r/mturk/comments/7tgxcf/requester_question_how_to_overturn_a_rejection/
