The problem is: the status in the right column does not even reflect the status in the loaded data. You can see the "experiences" JSON using web inspector in Safari, for example. Then you see that the status is completely different.
Hey poca,
how many Advanced Experiences does your app have? We have the suspicion that we maybe reached a limit.
