Ask HN: Google Services Reset

This week I experienced something strange and cannot find any other stories corroborating my assumption.

On several devices where I was not signed in to Google services, all of the “suggested” content (e.g. YouTube) was reset to a default state - no recommendations were made related to past interactions.

This was followed by attempting to login to my Gmail account, but my laptop’s browser was not recognized as trusted and none of my accounts were listed on the login page.

Has anyone else experienced this recently or in the past? Did Google perform some kind of global reset?
