Confirming this is still broken as of today (Sept 26, 2026).
On my instance the component now actively throws an error rather than just failing silently — Discourse shows the admin-only banner:
Posts may not be rendering correctly because one of the post decorators on your site threw an error. Caused by “Twitter/X Einbindung” [Twitter/X embed].
This keeps happening repeatedly and is triggering Safe Mode-style warnings site-wide, not just a missing embed. Discourse version: 2026.10.0.
Anyone found a fix or workaround beyond disabling the component entirely?
