Email disappears while I'm writing it
Several times now while I was composing my email it just disappeared without a trace in mid sentence. Once it was a long email so extremely annoying. No warning no nothing, just disappeared while typing (nothing in draft, trash etc)? This has never happened on other OSs (since Lion, when I got my first Mac) so I guess it has something to do with BigSur? I'm on a MacBook Pro.
This answer did not address the problem....
