Hello all, Following the Epic vs Apple court ruling early in the year, I find myself a little confused with what we can now do with third-party payment providers. Can I now offer subscriptions and payments for an app through my own custom built portal? The rules on it seem a little confusing surrounding the "you can email your customers to let them know you can pay externally" but I don't know how this would work for new customers. To provide some context, if I have a subscription system in place where new app users register an account and then select a monthly subscription and pay for it using a provider such as Stripe, is this now permitted? I'm based in the UK. Many thanks.

Hello all. I am looking at integrating IAP with my app but I am a little unclear on how I can do it fairly for my existing customers. Currently, if you would like that app, you simply pay the fee of £5.99 and it's yours. What I'd like to do is change it slightly so users who obtain my app in the future, can do so for 99p with limited features and then pay an additional £4.99 to upgrade it to the "pro" version if they like it. The problem is, I don't want my current users to have to pay for anything else. Is there a way I can automatically grant them the "pro" version without having to pay again?
