Automated Workflows Not Triggering

edited 10/27/22 in Smartsheet Basics

I have a very simple automation - email trigger when status changed. I has worked for over a year but suddenly stopped.

I have duplicated, edited and updated the workflow and no change. I did see mention of making sure your cells/rows were not at the maximum, but cannot find what that number is. We are over 1300 rows/entries, could this be the issue?

Thanks in advance for any help or suggestions!
