Well, as I've been saying all along, it seems there are still some bugs/issues with Big Sur, even V11.1. The beta for V11.2 was released yesterday:
https://www.macrumors.com/2020/12/17/apple-seeds-macos-big-sur-11-2-public-beta-1/No details on what is trying to be fixed. So far, my testing is proceeding very smoothly, although another real minor issue (with LibreOffice) has arisen (or I saw it for the first time earlier today). Not a show stopper, more like an annoyance.
