Dear All,We had submitted the app to app store whcih contains registration with email/ phone number and facebook as 3rd Party component, the app got rejected and its mentioned due to business payment, In-App purchase, but we dont have any business purchase / payment from the app or does not have any external link for it.. then explained our concern and got another reason from apple review team as below,"while we understand that your app does not use in-app purchases, since the app does not have a free long-lasting component prior to registration/ sign-up this would be considered as an external purchase mechanisms.To resolve this issue, it would be appropriate to remove the account registration or ad a free long lasting component prior to log in."In the app we are using only Facbook SDK ( FacebookCore, FacebookLogin, FBSDKCoreKit, FBSDKLoginKit, FBSDKShareKit) for sign up, Firebase for analytics and lottie animtaion library as third party components, As per my understanding facebook are completely free for the signup and other functionalities So we can't able to find the usage of above mentioned components.Please help us if you have any such experiance or solutions.Looking forward.Thanks
