I'd say about 1/4 of the movie is in Spanish, yet there is no translation to English. Where is the translation? Or has it been left off on purpose?
Same problem almost a year later
Try watching it on one of the other free channels/apps like Pluto, Tubi, Plex, and others that are carrying this movie (Get the Gringo) and see if you get the same issue.
Generally, using another channel/app, if available, is the best approach when you run into some issue on one of the others. Fixes just take too long for these channels/app to address, if they ever come, so best to just move on and watch elsewhere on the Roku platform.
