What's all this Devo Max stuff at this late hour ? And all the Queen nonsense?

Is this a real referendum? It's a bit hard to see what's going on from over here - Swedish foreign minister seems to be dead set against Scottish independence (though rather hypocritically is most vocal about Russia/Ukraine/Baltics)

can someone sum up the current state of play without me have to wade through a 300 reply thread
Please
thanks
