I have a multi-platform app in the review process. Two versions are in review. When I submitted the third one, for iOS, the system is asking me to answer the age related questions. The answers are the same as for the other platform versions but the 'SAVE' button is grayed out so the only option I have is cancel. That was a few minutes ago. Now there is an edited button and a View button on the App Information page. But, it still won't let me submit for review. I must be missing something but I can't see it.
Age related ansers required before review
After a week or two on revisiting the review page the question list was updated and I was able to submit the app for review after answering all the questions.
