Daniel Janik shows that query-level wait stats depend on the version of Management Studio:
The waitstats don’t appear at all in my older Surface which has a newer version of SQL. So what is 4202.2? It’s a refresh for Master Data Services and R. Could that really have broken my query plan waitstats?
I doubt it but maybe. I updated to make the two equal. Did the waitstats go away?
When reading the solution, it seems obvious, but this is a good reminder that there are a lot of moving parts here, and one of the early troubleshooting steps for “It works here, so why not over here?” types of issues is to make sure software is at the same version number.
