I started up RoastTime on my MacBookPro running Big Sur (11.1), as I always do. RoastTime notified me of a software update to ver 3.3.0, which I accepted. Now My laptop cannot communicate with the roaster. The ribbon on the right hand side of RoastTime cycles between ‘roaster issue’ and ‘roaster disconnected’. My Bullet was at the latest stable version. Since I can’t connect to it, I can’t tell you which version that is.
