I am logged into both my laptop (Windows 10) and my Android phone (Samsung S9). I have sync turned on and the information does eventually replicate from one device to the other; however, it can be as much as 72 hours before a website I've visited on my computer shows up on my phone history. I have taken to clicking sync manually before I walk away from my laptop in order to push my history to my phone. I've searched for settings where I might be able to change the speed with which my devices sync, but I can't seem to find anything.
