A week ago(7.9) we was publishing our office addin, and we uploaded our addin successfully. Today(7.16) we want to upload the same addin but get the follow error:enter image description here
If we added the "Authorizations" node at the Visual Studio, VS won't take that element and it would display error message to state that it is an invalid child element. Please see screen shot 
So it looks like that there is no "Authorizations" attribute in the "WebapplicationInfo" referencing this link https://dev.office.com/reference/add-ins/manifest/webapplicationinfo. and we are uploading the same add-in. Does anyone know more details to help us out?
