I have a problem with  the CW app, every time the commercials end the app abends (blows up) and displays and error message.  When i exit the app and start it up again I have to watch the commercials over again and often it doesn't start where I left off in the program.  I have the Apple TV 4K and all software is updated to the latest versions (including the CW app).  I've also reset the Apple TV and reloaded all of the apps.
