I read that article and didn't see the issue once I got to:
"If you toggle off “Web and App Activity,” which is enabled by default, Google will no longer be able to store a snapshot of where you’ve been from Maps data and browser searches that pinpoint your exact GPS coordinates.
As long as the Web and App Activity setting is enabled, Google will store your time-stamped location data. You can manually delete this data by heading into myactivity.google.com and clicking on specific geo-stamped entries. You can also delete batches of entries sorted by date or web service."
I mean.. hit the toggle if it's an issue.
