Adobe acrobat cannot recognise Samsung S-Pen and my hand.

Hi, I'm using Adobe Acrobat (version21.1.0.16863) on Samsung Galaxy Tab S7(Android 11). When annotating, I can write on PDF using S-Pen, and very awkardly, write using my hand. I cannot turn the pages with annotation tools on.

I also test with another app called XODO and it just works. It can differentiate my hand and stylus. But I really like Acrobat.

The tablet and S-pen work well and Adobe Acrobat was download from google play store. 

So I'm hoping for a solution on this. Thanks sincerely.
