Onesignal not working properly

Hello,

I’ve spent the last week trying to solve this problem.

I started a new ionic 2/3 project and I followed the steps of Onesignal website.
All works right, but sometimes the tag is not sent to Onesignal panel. This tag is very important because I’m doing a monitoring alert system with high life risk. If the tag is not sent the user can not receive the push notification with the alert message.

By the way, I do not know why but at home the device registration takes exact 5 minutes of execute and sometimes fails.

I’m testing on Android (LG G3)
