Issue with YouTube Caption Extension – Not Working Properly Recently

Dear Support Team,

I hope you're doing well. I’ve been using your YouTube caption extension for a while and really appreciate the functionality it offers—it's been a great help. However, I've noticed that recently it hasn’t been working correctly.

Specifically, the extension fails to load captions on videos . I’ve tried basic troubleshooting such as refreshing the page, reinstalling the extension, and testing on multiple videos, but the issue still persists. for example it only shows the title of sections on this video :https://www.youtube.com/watch?v=JoIBholrrfA&t=35s.

Could you please look into this? If there’s a workaround or an update in progress, I’d appreciate any information you could share.

Thanks again for your work on this tool. Looking forward to your response.

Best regards,

Ishak Cicek

Fehleranalyse
Der von Ihnen gefundene Fehler, parse chapters error SyntaxError: Unexpected non-whitespace character after JSON at position 374, ist der entscheidende Hinweis.

Was bedeutet das? Einfach ausgedrückt, versucht die Erweiterung, die Kapitelinformationen eines YouTube-Videos zu lesen. YouTube scheint jedoch das Format dieser Daten kürzlich geändert zu haben. Die Erweiterung "stolpert" nun über ein unerwartetes Zeichen, weil sie noch das alte Datenformat erwartet. Dies führt zu einem SyntaxError!
