Builds not being triggered from github pull requests

Is there something holding it up at the moment?

Ah my bad. I found there’s a default setting that disables building from PRs. All is good now!

Curious what this “default setting” is? All I see is Only build pull request under Advanced Setting, which I’ve enabled–but doing so actually stops all builds except for builds on master. This is the opposite of what I want–I want to ONLY build commits with a corresponding PR.
