Windows Phone の開発者が助けてくれますか? 私はWindows Phoneアプリケーションを開発しています。プッシュ チャネル uri を取得しようとすると、エミュレータでもデバイスでも問題なく動作しましたが、今日突然問題が発生しました。同じコードを使用していますが、エミュレーターとpushchannel_uri更新されたイベントのトリガーでは正常に動作していますが、Windows Phone からプッシュ チャネル URI を取得しようとすると、URI が取得されず、pushchannel_uri更新されたイベントがまったくトリガーされません。
私は使用Nokia Lumia 510しており、アプリハブで開発者として登録しています。
