I learned long ago to never upgrade an OS until every app I need has been demonstrated to be fully functional. Last year it took until late February for Izotope products to work with the 64 bit changes via Catalina (for which I might add BiaB was ready early on). I'm sympathetic to the frustrations expressed by many but I would politely suggest that caustic remarks bring nothing of value to the discussion. FWIW, etc., etc.
Happy New Year all!
