I currently have two apps on the app store right now but...
I believe that if its a suffix error, there isnt much you can do aside from regenerating certificates with a wildcard. (.*)
If you dont want to do that, just make a new set of certicates i guess ?
I suggest you save all your certificates and do not reject any certificates on apple developper side when you try any certificate changes...
Others might be able to help more, but i know i would probably just end up having two sets of certicicates (which is not necessarily ideal).
