Despite the fact that force-closing all the apps in your App Switcher isn’t the best of practices on the iOS or iPadOS platform, it’s still something that I continue to see people do time and time again.
Perhaps the most painful part of it all is watching when someone accidentally force-closes an app that they didn’t intend to – usually their most recently-used app which they were trying to improve the performance of by freeing up system memory in the process of force-closing all their other apps.
