I have completed the application except for anything to do with payment. Im not sure where to go from here. I have been beta testing but now Im ready to submit to app store. will there just be an option for users to subscribe when my app is displayed? or do I need to insert apples api or something into my app and then accept payment through stipe or something like that?

Hello, Im having an issue seeing my application appear in in testflight. as soon as i run the command eas submit - p ios --latest it completes and says Your binary has been successfully uploaded to App Store Connect! It is now being processed by Apple - you will receive an email when the processing finishes. It usually takes about 5-10 minutes depending on how busy Apple servers are. When it's done, you can see your build here: the app sometimes flashes on the screen in testflight then is gone forever This is an expo react native application.... I was able to submit builds but all of a sudden this started occuring.
