i remember at the new app release they said it will be updated to support language swap with chromecast, but this was in june? before june it worked..
for 2 months there was problems with casting live channels on the new app, thats fixed.. but still no update for the language on chromecast.. im waiting for that very hard like much others do.
it would be nice to get a update on this missing feature.. would be nice if a moderator would contact the app-team about this.
i dont know how long i will stay with only german on chromecast..
