Since the firmware update know as 1308 I have an issue that the update checker is not working so I have to manually check app by app. Do you know any trick to force the checker?
In Windows Phone 8.1, you can check for app updates manually from the Store app. To do so:
- Open the Store app.
- Expand the app bar by tapping on the three dots icon.
- Go to Settings.
- Scroll down, and under "App updates", tap the "Check for updates" button.
The number of updated apps will be shown in the Store app, as well as on its live tile if you have it pinned to your Start screen.
