However, it give me the capture below:

    Hi @developer sp1 ,

    Redirect to the SharePoint Online Admin Center appinv.aspx using this url:

    https://TenantName-admin.sharepoint.com/_layouts/15/appinv.aspx

    I stumbled on this same problem tonight and then realized the mistake I had made, which I believe is the same as the OP.

    The two step process has two unique URLs. The first:

    https://contoso.sharepoint.com/_layouts/15/appregnew.aspx

    is different than the one used for enabling the trust of the app

    https://contoso-admin.sharepoint.com/_layouts/15/appinv.aspx

    take specific note of the addition of the "-admin" after the tenant name in the second URL. Hopefully this clears it up for future readers.
