iTunes denies app updates
As the iTunes App Store matures from its recent launch, updates are becoming available for launch titles, but it is apparent that updates go through the same transfer method as other iTunes downloads, since an outstanding balance denies access to the updates. A MacNN writer noted that even though the updates are for software products they own, a billing discrepancy is enough to bar access to the updates, leaving users with buggy or incomplete software until the issue is resolved.
The writer observed that a slow credit card authorization allowed him to download paid applications, which were then declined by the credit card due to insufficient balance on the account. Since Apple can not pull licenses for purchased software, it leaves an outstanding balance on a user's iTunes account until the balance can be repaid.
Normally, this is to deter users from downloading excessive amounts of software when their card will not allow for it, it also affects the application update process, disallowing users to access crucial updates.
