Not able to remove or change .p12 certificate in Firebase Console

问题

I am using Firebase for sending push notification in iOS. After adding my .p12 certificate, Firebase will not update or remove certificate. Update popup is displayed but it will not make any changes.

Can anybody know how to resolve this issue.

Thanks in advance.
