Just set up a separate account, set up a simple event, on open of a door (smartthings multi sensor) send push notification.
Open the sensor, no push notification to my Android Device.
The log in the Android Smartthings app shows the event door opened at xx:xx so it is registering the door open event but I get nothing to push to the phone.
My phone is a Nexus 5 running Android 4.4.4
Push notifications work every other app that is installed and uses them.
