For a normal app it's hundreds of lines of stuff in the console. That's not the kind of thing one can ignore. This idea that it's just fine for Apple to dump noise into the console and then say "just ignore it" is simply wrong; it's based on a mistaken idea of whose console it is, when we are developing. Feel free to dump your garbage but not, please, in my yard.

@RawMean Thanks for finding that out, but the question still remains: what happens to me if I do not submit a version and I do not update the age rating, before January 30 or whatever. Is my app thrown off the App Store? Is it frozen forever at the current version? What?

If that's what the letter means, someone needs to teach the folks at Apple some basic English, because it sure doesn't read that way on any objective account.

I feel calmer already!

That does make the junk warning go away, but it's no kind of solution. The fix needs to come from Apple.

I'm doing exactly what you said, and I can't reproduce the issue. Can you post on github a minimal example showing how to experience the problem?
