Description of the issue:
I have been seeing search suggestions showing up in my search bar across devices that are not my own. These searches don’t show up in my devices’ search histories at all. I have confirmed that all the devices in my sync are my own, and I have deleted and started a new sync already but the problem persists. The search suggestions seem to look like they are my relative search history. However, they don’t have access to my devices at all (we don’t live in the same area). How did these searches being shown in my suggestion? I don’t want to see them
