Update 2014-10-13 15:15

I was able to "fix" this problem by creating a new Distribution certificate and then creating new provisioning profiles with that certificate. So it appears to be related to code signing.

While I no longer have a problem, I don't consider this to be a good resolution. I had to revoke an existing distribution certificate before the portal would allow me to create a new one. If we could create an unlimited number of certificates, then this would just be an annoyance, but being forced to revoke certificates for apps that are already in the field is not a good workaround.

I hope Apple can provide a fix or workaround that does not require revocation of existing certificates, or provide an explanation that convinces us that this problem won't recur.
