Browser support for CSS Grid

What's the browser support situation regarding CSS Grid?

I'm looking around and having hard time understanding the whole picture about compatibility.

If I go to Can I Use, it seems almost all browsers support it. But if I go to Microsoft documentation, the situation changes a bit.

It seems that almost all browsers support Grid but, except for Firefox, none of them support all the features.

Then, regarding Edge, I got that it only supports an old specification no longer used and the updated one is currently in progress.
