@PBK Hello, what about if you have test department which should test subscription workflow? How to test auto-renew subscription on device of testers which use AdHoc build. Also they want to change auto renew subscribe period over appstoreconnect accout, for control time of testing ?)

I think you found work solution, by the way: Task { await MatchHistoryController.shared.fetchMatchRecords() if Task.isCancelled == false else { return } await MainActor.run { [weak self] in self?.dataSource.apply(self.initialSnapshot(), animatingDifferences: false) } } But what about if you need to apply datasource in global queue, and do it in UIViewController which bordered as @MainActor :) I have got warn UICollectionViewDiffableDataSource is not @Sendable :)
