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)
Also make sure to use Google Takeout to download all of your data! It’s much easier to grab your old emails this way, plus lots of other data you might not even know Google had on you.
