I've been meaning to ask if you've actually been beta testing both 10.14.6 and 10.15.0 simultaneously? That seems like it would be insanely demanding and frustrating.
Good heavens NO! I may be crazy to be a beta tester, but I am not crazy enough to beta test two different MacOS versions at the same time.
