title: VSTS continuous integration triggers not working
body: <p>I'm pretty sure this setup was working at one point for  us. I changed our builds a bit to reflect some operational changes and now the CI git branch trigger isn't working. I'm trying to get it so when a PR is merged into master it triggers the release build. I can trigger this build manually but not when submitting a PR to master from dev and then accepting the PR (on github).</p>
  
  <p>Is anyone else having issues or know whats wrong?</p>
