@jezzsantos sorry missed this question. Please check conditional deployment

This doesn't work if you've got two builds running at the same time. Only the most recent build is ever returned. So, it doesn't work if you're doing a branch build and a PR build at the same time.

I would expect the https://ci.appveyor.com/api/projects/$env:APPVEYOR_ACCOUNT_NAME/$env:APPVEYOR_PROJECT_SLUG endpoint to return all running builds, but it only returns the one with the highest build number. :(
