I am not noticing any pattern. Sometimes, when I close the browser and open again, I am logged out of Google and YouTube only, other things remain logged in. And sometimes, closing and opening the browser doesn’t log me out.
I am mentioning YouTube separately because when I reopen the browser and I am logged out of YouTube and I can log back in by clicking the “Sign in” button. But for Google I have to enter my password each time when I am logged out.
The permissions and cookie settings for Google and YouTube are similar to other sites, such as Reddit and Facebook, which doesn’t log me out.
