iOS 9 has integrated a new system from Apple that allows us to quickly return to abandoned applications in case of accessing a link that took us out of that application and opened our Safari browser to display the page. In the attached image you can see what it is about, and in the upper left part of the screen you have a message that says Back to the name of the application, and when you press it you will return to that application, exactly in the menu you left.
The option is great because not all applications have an integrated internal browser and do not allow opening links, so accessing them automatically opens the Safari browser, so now we can quickly return to the application we left.
The option is available on all iPhones, iPads or iPod Touches running the iOS 9 operating system.
