Answer 1

You simply didn't deploy application to Azure. What you did is create a package for deployment.
- task: PublishBuildArtifacts#1
displayName: 'Publish Artifact'
inputs:
PathtoPublish: '$(build.artifactstagingdirectory)'
ArtifactName: '$(Parameters.ArtifactName)'
condition: succeededOrFailed()
It publishes artifact, but it doesn't publish your app to Azure.
Please take a look on documentation here
If you want to do this in the same job it would be like:
- task: AzureWebApp#1
inputs:
azureSubscription: '<Azure service connection>'
appType: 'webAppLinux'
appName: '<Name of web app>'
package: '$(build.artifactstagingdirectory)/*.zip'
Please remeber to provide all needed details.
