We recently improved our support for Requesters who want to approve or reject assignments in the Web UI via CSV upload. Now, Requesters can upload their CSV file with approvals and rejections any time after the batch has been loaded, enabling more flexibility and faster feedback cycles. This will allow you to pay Workers so they keep working on your HITs. You can even republish your rejected work while the batch is still in progress, resulting in faster project completion times.
We hope you enjoy this improvement!
