SAP Build Apps. Refresh or direct call to a page always goes to home page.

Navving from the home page (page 1) to another page from with the app works fine, but say for example I want to go directly to the following page.

https://ndbs-build.preview.eu10.apps.build.cloud.sap/114463/smart-requisitioning/page.Page3?projectId=2a583604-b448-4fbe-9417-118fb8cedaa7 (Page 3).

This redirects to my home page (page 1)

Also, if I’ve navved to to page 3 in the app and refresh the page, this too redirects to page 1.

Why?
