My app has been suspended

If your app uses content or an icon from another app, this could be the reason for its suspension due to impersonation. You should have received an email explaining the cause of the suspension. Unfortunately, there isn't much you can do since this constitutes a policy violation, and the app will remain suspended. However, if you believe your app is sufficiently distinct and you can make changes to address the issue, you might consider appealing the suspension via the same email to see if that resolves the matter.
