Delay of sending notifications?

Hello Everyone.

I was just wondering why it is taking more time to receive notifications. I tested OneSignal on June 12th, and notifications were delivered in seconds.

But when I tested today, it took me 20 minutes to receive push notifications since I sent it. I did not change anything.

Do you have any idea about this delay?

Thank you in advance.

Hi. Last night a bug in our system caused a notification backlog so some notifications were delayed up to 20 minutes from their scheduled time. This morning we identified and resolved the issue, so all notifications are now being sent promptly. Sorry for the inconvenience!

OK! 

Thank you for your answer! I will try tomorrow morning!
