We are working to move towards Cloud Manager for our CI/CD.
We are using process mentioned here:
https://docs.adobe.com/content/help/en/experience-manager-cloud-service/implementing/developing/aem-...

But although I am keeping the zip content packages under "install" folder, in Stage it is only deploying in Publishers but not installing in Author.

Package deploys fine in both Auth and Publish in Dev and QA which have single Auth and single Pub.
Stage have 1 Auth and 2 Pubs.

Any pointer..?
