I originally attempted using "Assign a task" to schedule my reminder emails if a task was not completed by the due date, but the task would not complete itself. Therefore, I need another way to send the Reviewer an email somewhere between where they are sent an email which assigns them as the Reviewer and the parallel block that waits for a change in the current item field.
I've read about the pause for duration option and then re-evaluating your conditions, but I wouldn't want to send the reminder email until 3-5 days after the original email was sent. I don't want the entire workflow to be held up for others who are also using the workflow process. (Hope that makes sense)
Here's a copy of the stage in my workflow. I have highlighted where I would need some type of condition and action.
