When i select the app through hub. it will redirect to the app where sheets are present.
It displays app information. But we have a option to hide after the page is loaded but Is their anyway while loading only it should hide the app information.
This seems to be an old post, but should you are using Qlik Sense, there is no option to remove or hide this. However In QAP, you can design your page though and can opt out not to include the app information.
