Can you please elaborate more on your workflow? The screen capture you attached shows a web map item, and not a web app item.
What kind of app are you trying to configure? One of the configurable app templates?
or a Web AppBuilder app?
Are you starting from the Portal map viewer or the My Content page to create a new app?
Thanks for your reply. I'm migrating the content between environments, I one environment I'm able to see an option for configure in another not able to see. Is this something related to enabling an option on the portal.
I'm still not clear on what app you are using, is it a configurable application template or a Web AppBuilder app?
> I'm migrating the content between environments ...
What do you mean by "environments"? From ArcGIS Online to Portal for ArcGIS? One Portal for ArcGIS instance to another Portal for ArcGIS instance?
As I mentioned, it would help if you could please provide details of your workflow.
