We are using 3.3.0.13.
We requested one person to review an article and he declined. I see the @hickeygamez queried this issue in Feb 22 and was told that an option to permit declined reviews to be reinitiated · (Issue #4789).
Does this functionality now exist?
For anyone who is reading this and using an earlier version such as we are, it is possible to modify the entry in the “review_assignments” table by changing the value for both “declined” and “canceled” to “0”. Mousing over “email reviewer” under the reviewer in question will display “review_assignment=xxxx” which is the entry that needs to be modified. I hope this helps others in my predicament.
