Screen reader won't turn off when I change language to English on HBO Max

Tani92163, if there's a voice describing the action in a video then it has nothing to do with the screen reader.  Try setting the audio track to something different either within the HBO settings or by pressing * on your Roku remote while the video is playing and going into the "Accessibility & language" settings.  Note that there may be two English audio tracks - one with description and one without.  If there's only one English track and it contains a description, then it's an HBO issue.
