Do the vBulletin mobile apps use Javascript-capable webviews to display threads?

Thanks for your reply!

Even if the apps themselves don't use javascript etc, I guess they could still render the threads in a (local) webview, even if they fetched the contents via the API, which would in turn make it possible to use HTML/Javascript in the post? Do you know it this is the case or not?

If the mobile apps do not use HTML at all to render the posts, how can for example custom BB codes (e.g. for embedding of video from custom sites) work and display correctly in them?
