I went through the Google Advanced Protection setup a few weeks ago. My only advice is that if you use Android, download the Smart Lock app before enabling Advanced Protection. If you don’t, you’ll get signed out of your Google account on your phone without a way to log back in (the Play Store won’t work without a linked Google account).
If you make this mistake, you need to then disable Advanced Protection, re-login to your phone, then download the Smart Lock app, and THEN re-enable Advanced Protection to get things working. Otherwise you’ll be locked out of your phone.
