Stuck in App

Hello alexandrafromflorence.

Thanks for reaching out to Apple Support Communities. We see that you would like to close apps that might be running in the background. We will be glad to assist.

Switch apps on your iPhone, iPad, or iPod touch

"Use Background App Refresh

After you switch to a different app, some apps run for a short period of time before they're set to a suspended state. Apps that are in a suspended state aren’t actively in use, open, or taking up system resources. With Background App Refresh, suspended apps can check for updates and new content. 

If you want suspended apps to check for new content, go to Settings > General > Background App Refresh and turn on Background App Refresh. If you quit an app from the app switcher, it might not be able to run or check for new content before you open it again."
