Right click and drag to adjust brush size is not working

[defaultyqx3xtxrojdx]

In Photoshop 22.4.2. (Apple Silicon) on my M1 Mac Mini running on Big Sur 11.4, adjusting the brush size while right clicking is not possible. 

When right clicking and attempting to drag-adjust the brush size it only shows the normal window where I have to manually set the size & hardness.

As I'm coming from Windows, where this always worked - did I miss something or is this a known bug?
