I currently have an app in the Windows Store that I plan to update to be able to host UWP extensions.
However, before I release this update to all my users, I'd like to have at least one extension available in the Store.
But I'm not sure how to get the extension to pass certification without first publishing my host app. Is it possible to use packaged flights but instead make them available to Microsoft for the certification process?
I could maybe release a separate "beta" version of this host app but if I can avoid it, that would be best.
