Symptoms

When running the registration wizard at the root site level of an O365 SharePoint instance, the following warning is shown:

"This application does not have permission to upload pages for rendering SmartForms in SharePoint. Click here to temporarily allow the application to upload these pages."
 

Diagnoses

Special permissions must be granted to allow Appit to upload the necessary template files used by SmartForms at the root site level.
 

Resolution

Clicking the "here" link in the warning message will surface a subform that asks for the URL of the SharePoint admin page, along with the credentials of the current Appit tenant admin account.

After submitting this form with the appropriate information, Appit will complete the registration process.
