Earlier in the week we heard that Microsoft had suspended the publishing of new Windows Phone apps to its mobile store, the apps were suspended due to a download bug.
Now it would appear that Microsoft has fixed the issue, and has resumed publishing of new Windows Phone apps to its mobile apps store, as it has now fixed the issue with the digital certificates.
We fixed the digital certificate problem and last evening resumed publishing new apps. It will take a day or two for the repair to fully deploy and newly-published apps to begin appearing in Marketplace again. If your app was in the process of being published, you don’t need to take any action. We have applied the fix and the app will continue through the certification and publishing workflow as normal.
You can find out more information on the issue of and the Windows Team Blog.
