Foreign media said that Microsoft has fixed the Win10 application in-app purchase system problem

Yesterday, users reported problems with the in-app purchase system of the WP8.1/Win10 Mobile and Win8.1/Win10 PC version of the app store, resulting in users not being able to use it properly. According to feedback from developers like Rudy Huyn, this issue is caused by Microsoft, not by application. Although Microsoft did not make a statement on the matter, the foreign media said that the problem has been resolved.

take version Win10 "My World", for example, we found that foreign media earlier today purchased application projects still can not be detected, and prompts the user to purchase. However, not long ago, foreign media found that the system has returned to normal, and the previously purchased projects have been properly monitored.
But it is still not clear whether the problem has been fully resolved. The MSDN Forum has no latest news about the incident. Users who are experiencing the same problem can now see for themselves whether the in-app purchase has been restored. (via:Neowin)
