Hi,
I noticed that captions are not working on the Commons videos (.webm files), although I have .srt files for the videos. For example, here is the video file (Commons file) and here is the Macedonian translation (captions), but still when you try to use captions in the file, you cannot find any captions, but you can create captions once again.
I tried to find any other similar issues, and as I did not find, I opened this task. --~~~~
