I am trying to catch up on three seasons of a show that has been running on the Audience channel. For some strange reason, some of the on-demand episodes can be downloaded to DVR, and others can only be viewed using the DirecTV app on my iPad. When I started viewing one of the episodes only available on the iPad, I invoked screen mirroring through my AppleTV 4K in order to view the show on the TV display. Almost immediately, while displaying “Optimizing Video quality”, the DTV app crashed. I tried several things, including deleting and re-downloading the DTV app, and trying a different on-demand program, but every time I tried to use screen mirroring, the app crashed. Is this a known issue that others have experienced?
