I have been using StoreKit2 for my projects before, which is troublesome. The first time I put it on the shelf, it was rejected because the subscription items loaded too slowly. After testing, it was approved because of network problems. Recently, I saw the beta module of Revenecat Paywall introduced in the independent developer community and thought about trying it. So far, it feels pretty good.
