Apple News may have more users than Apple itself estimates it has, Senior Vice President Eddy Cue has admitted. It has been underestimating the number of users of its News app ever since its introduction in iOS 9, due to an unexpected error that Apple is currently "in the process of fixing." This means that not only does Apple not know the true number of News app users, but the data passed on to publishers about its News-based readership is also inaccurate, potentially affecting advertising sales.
