I reset my kda9 to factory settings, and started again, and it resolved a few problems that had persisted from the last update. No longer have to keep resetting subtitles to off and so far no more muted streaming. So I hope that is resolved, and would recommend giving it a go. But although easy, it is time consuming signing back in to all the apps, and redownloading non standard apps: bit of a faff. Just hope we won’t have to do this every time there’s a software update.
