Describe your issue

Mouse over class has no effect.
Message form the extension in the "output":

[Info  - 17:35:51] [GLOBAL] No matching project for document {

}

I had the same after updating to TW v4. Disabling then enabling the plugin fixed it. Worth a try.

Defining "tailwindCSS.experimental.configFile" fixed the issue for me

No matching project for document

This tells me that IntelliSense isn't able to detect that the file that's open is inside a Tailwind CSS project (or more specifically that the file isn't covered by a Tailwind CSS config / CSS file).

Any chance you can provide a repro?
