How to split screen view the normal way in S21?

[matrixstar]

I've recently bought an S21 Ultra.

In my other phones, I split screen like this...

Hold down the recent apps menu button, immediately a split screen is opened and I can choose my other split screen.

On my S21 ultra, I I have to hit the recent apps menu button.

Then I have to swipe back to my current app and choose a button at the top of the window and choose split screen.

The, I have to go away and find another app that I want to split screen with.

PROBLEM: this is pants and takes one too many clicks. The old was is MUCH MUCH better.

If I'm watching something on Youtube for example, then my youtube thing I'm watching is paused.

Until a few seconds later, I have to give it another press to play again.

This is causing so much stress. Grrrr!!

What am I missing??

How can I get the old way back??

My previous phone was a Xiaomi. They got clever with the latest release and implemented similar to Android 10.

But, then you had the choice of going back to the old way of spliy screen.

Can I get what I want?

Thanks.

Edit I posted the same question for my s10+ phone. The answer was install good lock and then install Multistar. 

PROBLEM: multistar is not available 🤷‍♂ 

I've spent loooads of wasted time looking 

What am I missing? 

Is there another way?? 

Thanks

Have you looked at the settings menu ?? Then search for split.... it should be listed under advanced feachers

Thanks for the reply 

I looked at advanced options - the menu button long click is not there 

There is another shortcut though: drag 2 fingers up from the bottom. It's a bit fiddly, but it's better than nothing 

Why has Samsung messed around with multi tasking? Other phones are so much more intuitive to use.

(Not all phones though. The pixel phones are equally pants for multi tasking)
