Excellent news!
Randall, don't worry about turning on less-secure in the gmail account. That is simply Google's marketing pitch to get you to download the Gmail app rather than using Apple's Mail, or Outlook, or whatever mail app you are using. The Gmail app is no more secure that the one you are already using. They are just trying to scare you into turning all of your digital life over to them so they can send you even more targeted ads than they already do and sell your underwear size to Tommy Johns.
Glad you are up and running again.
