There is no excuse. Mackie stated that the only reason it's not available yet is because new apps take longer to get approved then updates to apps. The go ahead is there, now we just have to wait. That is if Mackie has not lied again.
And yes if road rangers assumptions are correct, which I am not sure they are, then a simple email would probably be all that is needed. It's not like Mackie has to go to apples office and press an "ok" key.
