Currently once a user purchases User Upgrade A, that upgrade becomes unavailable for purchase until the original subscription expires. This is problematic because this means the users are unable to renew before expiration. It seems like users should be able to purchase the upgrade again and it will simply extend the duration of the original purchase. As is, we have a lot of member confusion regarding this issue. Is there a way in the XF options to disable this functionality? I looked but didn't see anything. If not, is there any addon already developed to disable this?
