Hi there, I am here to ask for help regarding IAP and Apple Pay. So in my app, there are user two types, fan and athlete where a fan can ask the user text questions, or video questions or can directly tip the athlete(note: these questions are under the name of tip). I was using Stripe for payment but Apple rejected that and forced us to implement IAP by mentioning that as the question/tip is video/text based so you have to remove Stripe and use IAP. Therefore, I am here to ask whether I should use IAP or Apple Pay because in IAP we have limitations for predefined products while what if a fan wanted to tip a dynamic amount (here can we use Apple Pay for tipping) Please share your thoughts on what is the best way to tip while asking a question and free tip. One thing more to add we want to implement a bidding feature in the app as well where fans can bid dynamic amounts that IAP lacks). Thank you
