The Chinese side of the Windows Phone Store has had a bumpy time lately. For the last a few days, Chinese users have been experiencing problems when trying to purchase apps. Many found it impossible to download any paid app; you go through the payment process only to get an error message. The money gets accepted by the Windows Phone Store well enough, but the app license never comes. Some fairly persistent folks have tried repeatedly, paying $3 for Angry Bird Seasons in three shots. Yet they still failed to get the app at the end of the day.
