Hi,
I have developed an add-in for our company which basically loads part of our app into an iframe. This is fine, But we have a governmental customer whos users are essentially off the grid ie no outside internet access, The web-app portion of the add-in is
hosted on the internal web servers within the building but I am having trouble loading the add-in in their powerpoint app? is this due to having no internet access?
I'm aware that the manifest has a required link to schemas, for example: xmlns="http://schemas.microsoft.com/office/appforoffice/1.1"
would this be the cause of the problem? and if so is there a workaround? ie hosting the schemas locally
TIA
