Push Notification - Dev Mode not working



Besides not being able to delete registered push notification users on Ionic App, I have another problem:
Even having dev_push = true, it’s not using browser notification. It’s trying to load not dev mode and displaying pushNotification object errors because there isn’t instantiated.

Look my “ionic config info”:
dev_push | true
app_id | <my_id>
api_key | <my_api_key>
gcm_key | <my_gcm_key>

It’s everything well configured.

Please, help me.
