Fires before the first external storage read. Use this hook to register your storage provider via External_Storage::register_provider(). This fires after the connection package classes are loaded but before any connection status checks read from external storage. Useful for mu-plugins that load before the plugin providing External_Storage, since add_action() does not require the action or any classes to exist at hook-registration time.
Changelog
- Introduced in Jetpack 8.3.0
