my company had the exact same problem. This is no automated process. We had to enable EITHER in-app free trials OR in-app purchases (or both). And you cant use stripe, paypal, amazon payments, google pay, or alipay in-app.... it MUST be apple pay.
Yes, but I don't have it handy to quote to you. By the way, the forced use of Apple Pay is the really big anticompetitive behavior -- bigger than the forced use of the Apple App Store.
