The usual cause for this is an app crash. 造成这种情况的常见原因是应用崩溃。 I had it happen when my background refresh ran over the allowed 30 seconds. 当我的背景刷新时间超过允许的30秒时，我发生了这种情况。 Then the app appears to still be running when you reactivate it, but in fact it's restarted. 然后，当您重新激活该应用程序时，它似乎仍在运行，但实际上它已重新启动。

Check the device logs and see if you've had crashes like this. 检查设备日志，看看是否发生了这样的崩溃。 Given the date, you probably already solved your problem. 给定日期，您可能已经解决了问题。

Also remember that iOS calls for BG refresh when it wants, and it's very idiosyncratic. 还请记住，iOS需要在需要时刷新BG，这非常特殊。
