I just stumbled on this thread after a long battle with the rejection loop regarding subscriptions and in-app purchases, so leaving a mark here for devs in the future going through this. As per recommendations above, I've deleted current subs and in-app products, and created new ones until they went into status "Ready to Submit". I am re-adding the new subs/in-app purchases to RevenueCat and building a special iOS only page (because the app is made with Flutter) as I don't want to mess-up the other major platform purchases. Hopefully I can get the products picked up through RevenueCat from the App Store... I'll then build the app binary, submit it to review and append the new subs/in-app products to the new app binary. I am only unsure when should I submit the the subs/in-app products to review? Hopefully, all works and I get back to you with a positive outcome.
