IPv6 App Store Rejection

Question

Our update has been rejected twice today for ipv6 network connectivity issues. Our networking code has not changed between the previous release and this current release.

Answer 1

Our app is rejected the first time, we setup the local test environment based on apple document and find our curl lib is too old without enable ipv6 by default. So we build latest curl lib and it works. But it's rejected again because same reason. I check a lot information, find someone had same experience, just complaint to Apple reviewer to say your app works well in test environment and ask them to provide an engineer to help if they insist there is some error. Apple review team approved our app in the weekend when they saw our complaints.

As I know there are 2 issues you need check. Do you hard code ip address in your app? Do you setup your AAAA record for your server domain to show it supports ipv6, but your server doesn't listen to ipv6. If yes, just remove that AAAA record in your domain settings from your domain provider site.
