App Review Needed? - US External Payments: Dynamic Switch to Stripe

My app uses Apple IAP. With the recent US external payment changes (May 2025), I plan to use Stripe via Superwall. Superwall allows me to remotely toggle my paywall for US users between Apple IAP and Stripe checkout without a new app build.

Is it permissible to activate Stripe for new US users on an already live app version (approved with only Apple IAP) without first submitting a new build for Apple to review the Stripe integration? Or does this dynamic switch create a risk of takedown/compliance problems?

Concerned about new users hitting an unreviewed Stripe flow during any potential review period for a new build. Seeking clarity on Apple's stance or community experiences.

Thanks!
