Hi folks, anyone here who was worked on mobile apps with in app purchases? From what I've read, Play Store doesn't allow apps which use external payment gateways like PayTM, Razorpay for in app purchases but a lot of apps exist which use third party gateways and not the Play Store's IAP mechanism. Can anyone who has worked around this share any insights please?

Notice the section 3 of this page. It list the scenarios where you must not use google play's billing system https://support.google.com/googleplay/android-developer/answer/9858738?hl=en
