A user has purchased a subscription directly within the application on iOS but does not have the latest publication included - what could be the issue?
In this instance it is not a technical problem nor an issue, but most likely that the user has held a subscription previously where the publication has been included before.
For example, User A purchases a subscription in 2012, with the 'free' latest publication included within that subscription, but decides to cancel this in 2013.
In 2014, if User A decides to resubscribe, they will not receive the latest publication free with their subscription, however it will revert to the more traditional print method where the next publication is the one included.
