Can someone please tell me how the onesignal api really works step by step.  
I have got it to work on my app Loan. But after update the certificate/profile was invalid. And I am not sure how to update the app without all the certificate getting invalid all the time. Sometime I get this in onesignal ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/9/e914dd78c43ce2d45739e271e90b21d5737e72a9.png)  
How do I correct this.  
Base likely a update APP tutorial with AND without push notification…

Regarding the Provision profile tutorial it looks like this in the Thunkable tutorial
