Raindrop.io no longer fetches correct title and thumbnail from nicovideo.jp

Hi, I would like to report an issue with saving pages from nicovideo.jp (NicoNico, Japanese video platform).
Summary of the problem:
- Until around September 2025, Raindrop.io was able to correctly fetch both the page title and the thumbnail from nicovideo.jp video URLs.
- Currently, when saving a video URL such as:
the title field becomes just “ニコニコ” instead of the actual video title.
- The thumbnail is also not fetched anymore.
- Refreshing the preview does not fix the issue.
What I confirmed:
- The page does contain valid OGP tags (og:title, og:image), confirmed via browser DevTools.
- However, Raindrop.io seems to receive different HTML than what the browser shows.
- It is possible that nicovideo.jp started serving different content to crawlers or changed how OGP tags are delivered (e.g., inserted via JavaScript).
Expected behavior:
- Raindrop.io should fetch the correct video title and thumbnail from nicovideo.jp, just like it does for YouTube and other video platforms.
If needed, I can provide additional URLs or raw HTML responses.
Thank you!

Sorry about that. Fixed now, all new bookmarks will have correct meta data. The problem was Nicovideo started to harder detect bots and prevent parsing.
