Hey @Justin_Huang,
To make sure your app is still in review, I would double check your partner dashboard to make sure it’s still showing as in review (I’ve seen before where it wasn’t noticed that there were still steps).
I would also double check all of your email (including your account owner email, the app review email from your app settings and the emergency developer email). Often times our app review team will reply with clarification, but if that email is missed it can look like it’s stuck.
