dispatch.yaml not getting updated
Try

gcloud app deploy dispatch.yaml

...to connect services to dispatch rules.
I edited my dispatch.yaml and deployed on app engine using
 appcfg.py update_dispatch .
But when I go and see source code under StackDriver debug, I don't see the change.
Why the changes doesn't get reflected. But when I deploy complete app by appcfg.py update . the changes get reflected.
But in case, If I only want to update dispatch how do I do???
