Pattern preview is broken in PS Beta 27.1.0

Just as the title says, the pattern preview under View is broken and not working.

Still broken in 27.2.0.

UPDATE: I figured out what may be causing that glitch. 

Early access - prerelease 

I had flowcanvas, flowcompositing, and droverUI (both) enabled, and once disabled and restarted Photoshop and Pattern Preview was working again. So something within those tech previews disables the preview function, but turning them off makes it work again.

Hi @shaunaparmesan, 

Yes, Pattern Preview is not yet supported with Flow Canvas. It should be implemented in the next few weeks.
