Reporting an Issue or Missing Feature

When trying to upload files using add-PnPfile with a service principal made using the azure portal, it fails and returns an error of unauthorized or access denied, if the service principal is created using register-PnPAzureADApp it works fine, NOTE: both service principal were given the same permissions.

Expected behavior

I expect it to upload files irregardless how the service principal is created.

Actual behavior

Must be some missing configuration or something else ?
If it is unauthorized, it means there's something else that is missing when you create from Azure portal.
Check the difference between the one created by PnP and one by Azure portal, maybe something is different.
Moving to discussion.
