Can't download Mac OS Big Sur

Hi all!

So this is a very odd problem, but I simply cannot download the new Mac OS. I go to the app store, click download, the button grays out and nothing happens. No error message, no download, nothing. I have tried it more times than I can count, I've quit everything, restarted, cleared caches etc.

I'm using a 2017 Macbook Prof 15-inch on Sierra 10.12.6.

Any thoughts? Thanks!!
