My app has been determined to violate policy. As a result, my account was suspended on March 29th, and I was unable to log in to Facebook. Please let me ask you any questions.

Are similar issues occurring in other apps? How long does a normal review take? I am notified of the violation on the management screen, but not to the email address? Which value on the admin screen should I add my email address to? Is there no other way than to look at the management screen to realize that there has been a violation? Is there a way to get more information about revised terms and conditions in advance? What kind of subject and wording rules are used for alerts? The app was suspended 4 business days after the warning was issued. I think the lead time is short, but are there any plans for improvement in the future? Is there an API or interface available to check the health of Facebook login?
