How to disable multi tasking in iPadOS 15? And remove those pesky three dots that appear on top?

I am NOT running iPadOS 15, nor am I in any rush to do so.

There is always a way to turn OFF anything in any version of iOS/iPadOS.

You'll either need to download and install the iOS User's Guide to iPadOS 15 and find your answers there

Tap the link below.

OR

Search through the Settings App, until you find the correct option to disable this feature.

Good Luck!

The three dots situated at the top of screen are part of the new multitasking UI in iPadOS 15 and therefore CANNOT be removed.

In Settings app, look for the Home Screen & Dock settings panel. Tap and then look for Multitasking.

Tap Multitasking and then toggle OFF Allow Multiple Apps.
