Restoring application trust

Locate the TeamOrgChart application
Locate the TeamOrgChart app in your SharePoint tenant. It should be found under Site Contents.
Open the Permissions Page
Click the ellipses ( ... ) at the top right hand corner of the TeamOrgChart app to view the context menu. Then select the Permissions link at the bottom of the pop-up window. This may be hidden under the ellipses (...) at the bottom left of the pop-up dialog.

Finally click the link displayed at the bottom fo the page ( underlined in red in the picture ) to restore the correct application permissions.
