This is the video where I took the screenshot of the problem, but the issue occurs on all YouTube videos. I also tried the media file player feature, and it has the same problem as YouTube (no translation).
On YouTube, my location is set to United States, and my display language is set to English.
It’s been like this for about a week now, with no translations appearing. Before that, for about three weeks, translations were still working, but I wasn’t able to save any sentences.
My translation language is set to French (i’m learning English).
When I took the screenshot, the only extension installed in my browser was Reactor. I had also cleared my browser cache. I tried using a new Incognito window as well, but the problem was exactly the same.
