I posted about the first issue with BiaB after the Big Sur upgrade on the 13/11/2020. Others have been finding other problems as the weeks go on. It is now 2 months since the first problem was posted by me, followed by others, and still more are coming to light. Surely there could be a build update that took care of at least some of these problems?
