Z1544075226506 , via OnePlus 9 Pro , Jan 22, 2022 : Had a huge update last night to version C40 and there were a ton of changes. Now when I hit the Square button to bring up all the apps, Close all will leave apps open. I've also got several notifications that it couldn't close apps or asked if I wanted to leave some open... If you hold the button down, it will bring up a list of apps that you can lock, which I was thinking was keeping the apps from closing, but that doesn't seem to be the case... It's very odd. Ideas? Suggestions? Thanks!
