The answer will be yes to both, we're in the process of ensuring Big Sur OS is compatible for it's launch currently
I advise you not to upgrade to big sur until buildbox launches an official version with support I've been using a beta version of big sur for two months now I can't use buildbox, crashes when I open a new project
It still isn't working for me, I just get the spinning beach ball every time I want to open or start a new project
Right. We are preparing an update that resolves it. It will be released shortly, sorry for any confusion
