We would like to include billing functionality for the first time in this version of our currently released application. We have confirmed that billing is in place in local testing, In reality, the billing element has not yet been reflected in the store because it has not yet been reviewed by Apple. We have been informed by Apple that the billing elements will be reflected at the same time as the app review, We think this is a bit risky considering that the billing process may not work and the app may not pass the review process. How can we test the billing process for the store? Any better suggestions are welcome.

Hello. I am looking to publish an iOS app. I plan to start with a limited number of users that I specify, but the name and icon of the app are still in flux and have not yet been decided. Would it be a good idea to submit the app in this state from App Store Connect to App Review? It was mentioned that the app icon can be changed from App Store Connect, but not the name. cf. https://help.apple.com/app-store-connect/#/devfc3066644 This may not be appropriate since the application is not for testing, but would it be a good idea to use Testflight first? cf. https://developer.apple.com/jp/testflight/ Any advice is welcome.
