Thank you for post!
I understand that you are having trouble changing the URL for an application in your tenant and the registered app is not listed under Application Registrations.
By default, when you open the App registrations you will see the 'Owned applications' If the app is not
registered by you can see under the 'All applications' which as show below.
To change the Homepage URL for the application, you will need to edit the application object in Azure AD. Here are the steps to do this:
- Sign in to the Azure portal as an administrator.
- Navigate to the Azure Active Directory blade.
- Click on "Enterprise applications" and select the application you want to edit.
- Click on "Single sign-on" in the left-hand menu.
- Under "Basic SAML Configuration", click on "Edit".
- In the "Sign-on URL" field, enter the URL for the login page of the application.
- Click "Save" to save your changes.
