I have an app on the app store that was deployed with a certificate for an app id with a wildcard bundle identifier. Now I have to add push notifications to this app, resulting in exactly the same problem as described in this question.
The answers in the linked question say I should create a new app id with the complete bundle identifier. This is a problem, as the provisioning portal is telling me "The bundle identifier you have specified is already in use. Please select another."
I have looked at all the app ids, provisioning profiles etc. and the bundle id is not in use. Either someone else is using it or I did it some long time ago and deleted it.
What can I do about this?
Had to contact Apple developer support. After some weeks they figured out that the bundle id was taken by another account and were able to transfer it to my account.
