**[Problem/Question]**  
I created an iOS application that uses send bird to power a chat feature. Everything was working fine during development. Push notifications worked great on development builds. A distribution build was made and distributed via testflight. None of these devices are receiving notifications.

I navigated to the notifications settings and attempted to send a notification via the notification tester and got an error.

Is this an issue with the cert I am using or something else. I am using the same cert for Sandbox and Production.

Solved the issue. I had the wrong cert uploaded.
