Why am I receiving the message "All included players are not subscribed"?

The "All included players are not subscribed" message could mean any of the following.

1. Ensure you have set the correct app_id.
2. You have no subscribed users.
3. You haven't setup a platform for your devices on the App Settings page on OneSignal's dashboard.
4. There are no users in the filter.

In your case the location is probably more than 1,000 meters away. Try increasing the radius and confirm that you see a "Location Point" on the All Users page on the OneSignal dashboard.
