‘HDCP Connection Standards Error with FaceTime SharePlay of Amazon Prime

Trying to SharePlay via FaceTime between two fully updated devices with different Amazon Prime Accounts to watch the same show. Same error every time means that the screen is black for at least one user and audio will occasionally play but usually won’t either. Error message will always appear for the user attempting to share the video. There’s no HDMI cables involved or anything that could create this error, but it occurs between iPads and IPhones in every combination. Any help is greatly appreciated.
