Would a VPN fix that since Google would never see your true IP?
Depends. I’m sure their ‘cookies’ have amassed a lot of profile data.
I’m in the process of migrating to a new laptop, so a new profile ‘may’ do it in conjunction with a new IP from my ISP...if I don’t ever use my legacy gmail address - a secondary email - from the same laptop.
What’s concerning is that I never had these problems while I had FB (started after I deleted my account).
