I'm working with a client who just set up a new SharePoint 2016 site on their server. They created an App Catalog but when I load in a custom SharePoint App, the App Catalog doesn't read in the version from the AppManifest.XML and sets the version to 184.108.40.206 nor is the app assigned a Product ID - the Product ID is left blank.
The same App is uploaded with the correct metadata on other sites.
Is there something that needs to be configured so the App Catalog library behaves like an App Catalog?
Thanks in advance
