The Agreements button started working again shortly after my previous post.

You should be able to click on the big Agreements, Tax and Banking button below to access the new agreement, but for me clicking on that button just returns to the main ITunes Connect page after a few seconds. I've tried two different browsers on two different computers with the same result. Is anyone else having this problem?

They're referring to the rating that customers give your app, not the age rating of the app. If you've gotten a lot of good reviews and ratings in the past, you probably want to keep the existing rating. If you've gotten a lot of bad reviews and ratings, you may want to reset the ratings.

What he said, plus approval of other apps by Apple with similar features has no bearing on whether or not your app will be approved.

Yes, deleting the app from the App Store has no effect on the app installed on the user's device.

They are VERY different. If you delete the app entirely, you lose the use of that name forever although other developers are free to use it. I would strongly recommend not deleting the app unless you really don't want it anymore. If you remove an app from sale, you can easily put it back for sale without having to go through app review. In both cases, it has no effect on existing users of the app -- they will still be able to run the app on their devices.

This problem has already been discussed extensively on this forum. There is nothing you can do except continue to wait.

If you simply remove it from sale, yes. If you delete the app completely, you aren't allowed to create a new app with the same name (although every other developer would be allowed to use that name).

I'd be surprised if Apple approved something like that. It would be too difficult for them to follow up and make sure the other apps were deleted as promised.

They're basically saying your app doesn't do anything that can't be done with a web page. It doesn't have any features that take advantage of the Apple platform.
