I just had a few questions to follow up on your post:
- Is the LR extension in your browser toggled on?
-
Does the video you are using the LR extension have subtitles/CCs in the languages you are looking for (the language you want to learn and the language you want it translated into)?
-
Did you check your settings using the
settings icon next to the LR logo in the tool bar of your video?
LR Settings Icon
Settings Example 1:
Settings Example 2:
As long as the subtitles are available for those 2 languages you want, dual subtitles should still work for you.
Additionally, for the most part (if you’re a Pro subscriber to LR), as long as your video has your target language subtitles and your settings are matched up with the video, you should be able to toggle on machine translations to see two sets of subtitles that way.
P. S. If you are still experiencing issues. Screenshots of your LR video settings and subtitle section with LR toggled on might help to pinpoint what might be going wrong.
