Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I watch Amazon Prime video on my on my TCL 65s425-CA with built in Roku 7133X, software 184.108.40.20602 and the sub titles are all over the map. I’ve selected English, and no captions on both the Amazon settings and the Roku settings. I get everything from different languages to descriptive style subtitles that note background noises.
Prime Video is really the only problem for the TCL/Roku combo.
