When I make changes to my bitbucket-pipelines.yml file the Pipelines doesn't see the changes.
I'm working on master. I've tried editing the yml file directly in Bitbucket. Pipelines sees a new commit and begins executing but the operations that are executed are from an old yml file.
When I click the gear icon here:

I see the new/updated yml file. But the Build panel to the right of that shows commands from an old yml file are being updated.
I've made a number of commits to the yml file now. None of them have been picked up by Pipelines.
Has anyone encountered this issue? Any suggestions of what to try to resolve it?
