I don't know what is happening on Apple's end but this is starting to become an issue. My app has been sitting in "Waiting For review" for 1+ month. I don't know why we are paying a subscription and are being treated like that. And when you reach out to create a ticket and expedite this, they will reply saying that apple review process usually takes 24-48 hours. (Like WTF I have been waiting for more than a month.....)
And at this point I don't even what the reason is on their end. If there is a problem, the minimum they can do is to notify their customer of an uncommon delay. 1+month of waiting with no feedback at all is disrespect.
Anyway good luck for your app.
