I didn't think this warranted a full blog post/announcement, but I wanted to let everyone know that over the past week or so, the Payment Required flag setting in app submissions has not been persisting, so even though some of you have selected "Yes" when submitting your apps, they come to us with the option set to "No." This has led to a number of app rejections requesting the Payment Required flag to be set to Yes, and several of you have attempted and failed to comply because of this apparent bug.
After I realized the flag was misbehaving, I paused app approvals since there have been quite a few queued up that should be marked payment and I didn't want to put anyone through any more frustration. :) I've received word that this option should be working properly again, so some of you can expect to see some app rejections today requesting the payment required flag to be set.
Apologies for the trouble with this, and I appreciate everyone's patience!
