Multitasking
How do I minimize a web page and open other web pages or apps and multitask?
iPad Pro, iPadOS 15
On your App, you can click on the 3 dots at the top to launch the multi-tasking widget.
Alternatively, you can choose to launch another App first. Swipe up from the bottom to reveal the dock. You can drag you App to your screen.
Now you have 2 Apps on the same screen. In this example, I have 2 Safari windows.
