I have several subscription plans in the App Store that I no longer wish to offer to new users. In my app, these old subscriptions are hidden, but they remain active so existing subscribers can continue their plans and be charged as usual.
However, some new users are still able to switch to these old subscription plans through the App Store.
What is the best solution for this situation? I want to continue serving existing subscribers while preventing new users from subscribing to these legacy plans. Thank you.
