Hey @jesse_epstein, the reviewer pushback is likely coming from your shopify pricing not matching the pricing of your website.
Take a look at this thread here as it’s the same scenario you’re running in to: Clarification on Billing Requirements — App Using Stripe for Subscription & One-Time Charges (posts 2 and 4 are the relevant ones).
The TLDR is that we expect merchants to have a path to install your app and use it’s features without needing to set up separate billing outside of Shopify. For cases where merchants have their billing already set up with you and are adding your app to their store, switching their billing is not required.
