Haven't tried. Can't risk it since it runs my company. A lot of people complaining on the QB community about not being compatible but for whatever reason we had one person accidentally upgrade to Big Sur and it's running, but they are not hosting the server file, which is on my computer. I'll just wait until they officially say.

They just had an update a couple days ago but it didn't mention it. Weirdly enough, the one on Big Sur had an update where it did mention Big Sur compatibility but QB still does not list 2019 as compatible and the update numbers are not the same between the two. I'd rather be way safer then sorry in this situation.
