I'd like to clear my Gmail search history. I saw this video, and thought it would help me: https://www.youtube.com/watch?v=ReYtFia-uCU
But it doesn’t. The item in question I want to delete doesn’t have the clock icon nor an "X" next to it. It's got a magnifying glass. But deleting all my Google history from all time, and stopping Activity History, has not helped.
