Same problem here. Submitted a new submission and new submission is in review but subscription products are still waiting for review. sent an email to review team and looking forward to be solved this.

Hello, could you please share whether they approved after you contacted to them? What is the current status of your app?

I'd like to share an update for developers who has similar problem. I had same problem and after, I replied app review's message to describe our app is not a spam app and the app status changed to in review few minutes later and it's been approved. I believe sometimes these kind of misunderstandings may happen. After we describe the product to the review team, they reviewed it again. thank you.
