this location timeline page https://timeline.google.com/maps/timeline should be included up along in there. if not deceptive, it's certainly badly designed and confusing enough for you to overlook what options are available to you. in dark mode, these little buttons (that actually manage your data and obscure important options) are almost unnoticeable. and this is somehow the only way to delete your location data, both web and mobile. even on android it's still just a redirect to that same web page. there is no native 'delete location history' button. (and if you do open that page on android, you might have to sign in to your account again before even seeing anything lol. as always, burying and obscuring controls. it couldn't be that hard to implement a 'delete all' button on activity controls page right before, but oh nooo, what if people would actually deprive google of location data.)
