Hi there, thanks for reaching out. Sorry for the late response due to New Year Holiday.
Since iPad Pro 11′'(2021) has fewer speaker holes than the 2020 version, we adjusted the cutout on the new case accordingly. Besides, there is a little unfitness around the camera if you put the MagEZ case 2020 on the iPad Pro 2021.
Therefore, we will suggest the new case for iPad Pro 11′' 2021 if you want a perfect fit case.
If you have any other questions, please feel free to contact us. Thank You!
