From NewCrop:

There was a bug today (it will be fixed over the weekend) from what our Tech Support tried to do last night. We are attempting to allow providers that have been sent to webcam proofing another shot at proofing (a second attempt). The bug isn?t allowing a second try or scheduling for the webcam, whichever is appropriate. They should wait until Monday when the bug is corrected or they will keep seeing this error. The provider should be able to start with either their proofing or webcam on Monday. It?s great that he has the Authy app on his phone ? that will make the rest of the process that much quicker.
