This question already has an answer here:
I understand that this question is related to a workflow of a journal and have tried to look at the answer of this specific query but am not able to find a specific answer anywhere else. The query is I had send a paper to a reputed journal. Its status for the past month was "Review in progress". After more than a month, its status changed to "Ready to review". What does this mean? How could the status for atleast one month be "Review in progress" and then change to "Ready to review".
