Maybe you should provide more information other than a screenshot.
New users who install The aplication do not receive my push notifications this happens to me since i started using makeroid in appybuilder if it worked, in The imagen i see that error in onesignal. There are more than 100 users who have subscription error to my app.
Edit your topic, this is a bug.
bro removed the onesignal from the app for the few days i also face this problem on last month
