I can reproduce this: if you send this link to the Embedly Extract API: https://www.msn.com/en-us/news/politics/as-advertisers-flee-musk-s-x-democrats-splurge-on-political-ads/ar-AA1lk0gR
It returns a provider_url of https://www.msn.com/. This has happened with multiple valid MSN article URLs.
Any ideas?
