Turning on one caption track will blind the other tracks. How on earth do I have to show subtitles in multiple countries on the screen at the same time? Please update again so that multiple captions can be applied like in the previous version.
There are UserVoice requests for that. Which is clearly needed. So go to the UserVoice service and search for captions or multiple captions requests. There are several it would be nice if you would upvote.
This forum is user-to-user peer help, volunteers primarily like myself. The UserVoice system is their setup for generating metadata for user interests, which is used by the marketing & experience people who are 'above' the program teams ... and actually seem to make the main decisions for adding features by setting budgets.
