Adding on-demand resources in new app versions.

We are seeing an issue where the list of ODR tags doesn't seem to be updated when app upgrades. For example, let's say in v1 of our app, we defined a tag "foo" with associated resource and everything was working fine. Now in v2, we introduced a new tag "bar" with new resource. What we are seeing so far is that for people who have installed v1 and then upgraded to v2, the request to begin access of "bar" will return success, but the actual resource is never downloaded, so the app will fail to gain access to the resource. However, for people who installed v2 directly, or uninstalled v1 before installing v2, the new resource will download fine. It's obviously an unnatural experience to ask our users to manually uninstall our app before upgrading it, so we are wondering if anyone has seen this issue before and can shed some light on how to deal with it properly. Thanks!
