In my work, we have an application ready and we want to put it into the App Store. The application is usable only with clients that are pre-registered to our service. We recognize them by their device's MAC Address (we don't use e-mails and passwords).
So, the problem is: Since in order to test the application you are required to have your device pre-registered using its MAC Address, how can Apple test it since we don't have their device's MAC Address pre-registered?
Therefore the actual question: Is there any way to tell apple to contact us for pre-registering their test device prior to actually testing the application?
PS. I know that there is the "developer notes" field in iTunesConnect when you submit the binary, but is that the only way of contacting the App Review Team for such reasons?
I will respond my own question, since I have stumbled across this lately.
Short answer: Can't be done. We have developed a workaround that will allow anyone with a specific build to login in to a test account even if he is unregistered and his MAC address is not recognised. So, the old versions remain intact, and the new version waiting to be accepted is actually a wildcard allowing anyone to test it, in this case, Apple.
It's the only way.
