Added schema cannot be obtained with flexibleSyncConfiguration

MongoDB Atlas App Services & Realm Atlas Device Sync
1

I added a new schema on the console and added code to the existing app, but I could not get the data.
However, once I reinstalled the app, I was able to successfully retrieve the data.
Since the app has already been released, I would like to be able to successfully retrieve data without having to reinstall it, but what could be the cause of the problem?

sample code

var config = realmUser.flexibleSyncConfiguration(
                initialSubscriptions: { subs in
                    // MARK:  setup User Datas
                    if let _ = subs.first(named: "users") {
                        return
                    } else {
                        subs.append(QuerySubscription<Users>(name: "users"))
                    }
                    if let _ = subs.first(named: "new_data") {
                        return
                    } else {
                        subs.append(QuerySubscription<NewData>(name: "new_data"))
                    }
            })

config.objectTypes = [
                Users.self,
                NewData.self
            ]

realm = try await Realm(configuration: config, actor: RealmActor.shared, downloadBeforeOpen: .always)
