Hi,
The new Private Space feature allows you to hide it, so that other people can't see that you are using it. The only way to then open the Private Space is to go to your app library and type Private Space in the search bar. You can also access it via the Security and privacy settings. However, for some reason the Private Space doesn't show up for me if I search for it in the app library. Does anyone else have this issue? I'm also using a Work profile that is managed by the Insular (Island) app but I'm not in the position to delete it and test the Hidden Private Space feature without the Work profile. I'm using GrapheneOS on a Pixel 6 with the most recent 'Stable' update.
