Hey there Aj1,
Welcome to the new Nest community forums! We can take a look into this subtitle issue and see why they aren't playing, let me just ask you a few questions, so I can understand the scenario:
- What model of Chromecast do you have?
- Have you tried casting from the Vi Movies and TV's application and website?
- Are you located in a supported country?
Depending on what kind of Chromecast you have, as well as the file type that Vi uses, could affect the Chromecast's ability to display subtitles. Here is a similar thread from a while ago that explains it in a bit more detail.
Aside from that, if you are also not located in a supported country, the Chromecast may not function 100% as intended since it would be using unfamiliar apps, internet, and software from the TV.
I look forward to your response, and if you had any more questions or concerns, please ask!
Best regards,
Jeran
