Does your WordPress site show THIS:
Instead of your embedded video?
Well, instead of an AI generated 10 page article describing how you need to load a special 3rd party paid plugin that will fix nothing… You just need to re-enable it with Jetpack:
Find this setting under Jetpack > Writing > Composing > Compose using shortcodes to embed media from popular sites
Hopefully someone will find this, find this useful, and fix their WordPress short code issue where it’s not working because JetPack toggled this feature off. This is the sound of me screaming in digital.
