I still use gmail and drive for work but otherwise I’m never logged into anything google at home. Today when I tried to expand on a restaurant’s hours it wouldn’t let me see them without logging in, although it still worked in incognito. This restaurant screenshot is just a random other example I tried, but for the one I was actually checking google had the correct hours while the official website hasn’t been updated in awhile and had the old ones (website said they’re still open for dinner but they’ve only been doing lunch for a year or so now)
The only stumbling block I have found is that I have a couple accounts where my email address is my sign on and it cannot be changed. I would need to set up a new account with my new email address.
Other than that, it’s been like you said. A bit daunting at first but one day I’ll break that chain and never look back.
