[Enhancement] Secondary subtitle doesn't sync with the content when using the Advertising standard membership

Hi! First of all, thanks for making this awesome program. I'm one of the users who's been really enjoying using this extension.

So recently, I switched over to the Advertising standard plan, and I ran into this little issue. The thing is, the second subtitle just keeps showing up even when the ads are playing, and it's not syncing up with the main content once the ads are done. So I have to refresh the page every time after the ads. Hope the subtitle can stay in sync with the video 👍

Thanks!
