Can I detect subtitle changed if user change it by system menu on roku?

I try to update my custom player UI when user change subtitle.
Property subtitleChanged changed when I set subtitle by setSubtitle method, but if I change subtitle by system menu ( press * on remote controller and change subtitle ), the property didn’t change.

Is it possible to detect if user change subtitle by system menu?

Thank you.

Hey there,
subtitleChanged functions as a confirmation event for when you change the subtitle track using our API, as you already observed correctly.
Currently there is no way of detecting a subtitle track change by the system menu, which obviously isn’t ideal, therefore I’ve already created a ticket to add this feature.

I’ll keep you posted here once it’s implemented.

Thank you for replying.
