Unable to switch connections on open document

I’m using Toad for Data Analysts 3.1. I’ve built a query via the query builder, but I would now like to run it against a different connection. According to the help, I should be able to right-click the tab of the query, but I find that this option is only available on a new tab that doesn’t have any query criteria. I’ve also tried clicking the connection on the bottom-right, but no luck there, either.

Both connections have the same tables.

Why wouldn’t I be able to switch connections on a built query?

Changing the connection from a right click of the tab was added in a later version. Please try the Beta or upgrade to latest version of TDP (3.6.1)
