WP 8.1 Silverlight App - Clicking reminder no longer launches app

[Suggy]

Hi, has anyone else seen this problem or know of a fix. Since I migrated my silverlight app to WP8.1 the OS no longer launches the app automatically when the body of a reminder is clicked. It did this fine in 8.0 but for some reason it stopped working in 8.1.

Reminder as in a Toast notification?
