Hello. My friend and I might have found a fix. But further testing is required. Instead of using SubscriptionStoreView(groupID: "someGroupId"), try using SubscriptionStoreView(productIDs: ["someProductId1", "someProductId2"]). We tested it on my app on 2 devices: the old version shows "Unavailable", but the new update works. Check SPEEDCUP's latest answer in this post for more info. Could you try using productIDs instead of groupID in your app and let me know if it solves the problem? Thank you!
