I did the release2021 update, and now my microsoft 365 isn't backing up

I did the update, and because it created a new icon, the microsoft 365 isn't backing up to the "cloud" anymore, before when I called, i had to right click on the icon and run as administrator and then I got into the area to change network to private, and i don't remember how to get to that area, can you tell me how to do it please?
