On Demand shows cutting off ending

Trying to snag a show in the on demand area, when it plays it cuts off the ending and moves onto the next episode. I am using firestick on smart Tv--not a tablet or phone. I have done this:

• Check for app updates in your app store. If an update is available, install it and restart your device.
• Check for device software updates and install.
• Close and restart the DIRECTV STREAM app.
• Reboot your phone or tablet.
• Uninstall and reinstall the DIRECTV STREAM app.

I tried on my laptop.  If I click the episode icon with the play arrow then,  it gives me a blank teal screen with a back arrow in the upper left corner.
