los2cos2gos OK, thanks, but if I have a private space, I do not seem to be able to switch to another (non-private) profile simply by swiping quickly twice.
Not sure I quite know what you mean. If the private space is unlocked, you can still swipe down from the top of the screen twice and switch profiles.
simply by swiping quickly twice.
Unless you think by swiping down twice quickly switches profiles? It does not, you have to swipe down twice and click on the little person icon. Not sure if that's what you meant by "simply by swiping quickly twice" but just to be clear, you can't do it by swiping quickly :)
Also, Oggyo 's post is helpful. Apparently you can have private spaces in more than one profile. I just wasn't aware of that
