I installed 3 a day or two ago (nice!), but it has become unresponsive while publishing (twice). Generally, I just change something on a page like a new version of a video and publish it. It uploads a lot of stuff including the new video, but eventually stops. I have 32 G of memory and Sparkle is using all of it plus disk caching. I’ve had to force quit Sparkle twice to get it back. Also running Big Sur. What do you think?
